Unexpected error occurred while launching entry - pentaho

I have implemented a loop job in pentaho kettle. This job has "Simple evaluation" entry that checks if it should rerun the previous transformation or not based on a condition. The variable used in condition, is being set using "Set variable" step in previous transformation. The problem is that first time job runs perfectly, but when server is restarted, job stuck and throws error:
Unexpected error occurred while launching entry.
This error comes for both transformation and "Simple evaluation", and then job stuck in loop forever.
So I have two questions here:
Why does this error occur?
If an error occurs, transformation should stop but it is forwarding the flow to "Simple evaluation" and vice versa.
Below is the image of job :

Load from GCS to GBQ causes an internal BigQuery error

My application creates thousands of "load jobs" daily to load data from Google Cloud Storage URIs to BigQuery and only a few cases causing the error:
"Finished with errors. Detail: An internal error occurred and the request could not be completed. This is usually caused by a transient issue. Retrying the job with back-off as described in the BigQuery SLA should solve the problem: https://cloud.google.com/bigquery/sla. If the error continues to occur please contact support at https://cloud.google.com/support. Error: 7916072"
The application is written on Python and uses libraries:
google-cloud-storage==1.42.0
google-cloud-bigquery==2.24.1
google-api-python-client==2.37.0
Load job is done by calling
load_job = self._client.load_table_from_uri(
source_uris=source_uri,
destination=destination,
job_config=job_config,
)
this method has a default param:
retry: retries.Retry = DEFAULT_RETRY,
so the job should automatically retry on such errors.
Id of specific job that finished with error:
"load_job_id": "6005ab89-9edf-4767-aaf1-6383af5e04b6"
"load_job_location": "US"
after getting the error the application recreates the job, but it doesn't help.
Subsequent failed job ids:
5f43a466-14aa-48cc-a103-0cfb4e0188a2
43dc3943-4caa-4352-aa40-190a2f97d48d

f25ba358-7b9d-455b-b5e5-9a498ab204f7
...
As mentioned in the error message, Wait according to the back-off requirements described in the BigQuery Service Level Agreement, then try the operation again.
If the error continues to occur, if you have a support plan please create a new GCP support case. Otherwise, you can open a new issue on the issue tracker describing your issue. You can also try to reduce the frequency of this error by using Reservations.

LeaseAlreadyPresent Error in Azure Data Factory V2

I am getting the following error in a pipeline that has Copy activity with Rest API as source and Azure Data Lake Storage Gen 2 as Sink.
"message": "Failure happened on 'Sink' side. ErrorCode=AdlsGen2OperationFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=ADLS Gen2 operation failed for: Operation returned an invalid status code 'Conflict'.

The pipeline runs in a for loop with Batch size = 5. When I make it sequential, the error goes away, but I need to run it in parallel.
This is known issue with adf limitation variable thread parallel running.
You probably trying to rename filename using variable.
Your option is to run another child looping after each variable execution.
i.e. variable -> Execute Pipeline

or
remove those variable, hard coded those variable expression in azure activity.

Loop exit not working

So I have a workflow which is supposed to throw an error after a certain condition is satisfied. (False condition) As you can see in the log directly below, it works: I do a loop exit first for the group 'coms' and an error is thrown. However, Flowgear seems to only read the last executed node and then determine the workflows status from that. Since the loop finishes last and is successful, if you look in the second log, you can see that the workflow has been evaluated as 'successful' although an error was thrown inside.
Any ideas how to make the loop break? Also why does flowgear only consider the last node? There should be an option in the error node to stop all execution.
Iterator nodes (Splitter and Loop) will consume the errors. The only way at this stage to get the workflow to return an error is to cause an error in the AnyError or UnhandledError part of the workflow. I've created a workflow to demonstrate this here: http://flowgear.me/s/UdpGBbd
Hope this helps.

SSIS CSV Import Error 0xC0202092 DTS_E_PRIMEOUTPUTFAILED

All of the sudden, a CSV file that is imported into a db/table every morning is failing every time within the last few weeks. I do not support this process directly, so I don't know much about SSIS, but would greatly appreciate some help as I need this working and whoever supports this process has no idea what the issue is. I'm not sure if that error regarding the row has anything to do with the data in the row because it looks fine to me. The CSV includes Active Directory information for every computer in AD and is exported from PowerShell to a server where the CSV is imported into a table via SSIS. The process is entirely automated and nothing has changed.
[Source - Clean_Gold CSV [1]] Error: The column delimiter for column "LastLogontimestamp" was not found.
[Source - Clean_Gold CSV [1]] Error: An error occurred while processing file "H:\Computers\clean_gold.csv" on data row 40377.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on component "Source - Clean_Gold CSV" (1) returned error code 0xC0202092. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.
I looked at 40,378 and saw someone put a ", in the description of the computer object in Active Directory. That caused an issue with the delimiting.

Determine actual errors from a load job

Using the Java SDK I am creating a load job for just a single record with a fairly complicated schema. When monitoring the status of the load job, it takes a surprisingly long time (but perhaps this is due to working out the schema), but then says:
11:21:06.975 [main] INFO xxx.GoogleBigQuery - Job status (21694ms) create_scans_1384744805079_172221126: DONE
11:24:50.618 [main] ERROR xxx.GoogleBigQuery - Job create_scans_1384744805079_172221126 caused error (invalid) with message
Too many errors encountered. Limit is: 0.
11:24:50.810 [main] ERROR xxx.GoogleBigQuery - {
"message" : "Too many errors encountered. Limit is: 0.",
"reason" : "invalid"
?}
BTW - how do I tell the job that it can have more than zero errors using Java?
This load job does not appear in the list of recent jobs in the console, and as far as I can see, none of the Java objects contains any more details about the actual errors encountered. So how can I pro-grammatically find out what is going wrong? All I can find is:
if (err != null) {
log.error("Job {} caused error ({}) with message\n{}", jobID, err.getReason(), err.getMessage());
try {
log.error(err.toPrettyString());
}
...
In general I am having a difficult time finding good documentation for some of these things and am working it out by trial and error and short snippets of code found on here and older groups. If there is a better source of information than the getting started guides, then I would appreciate any pointers to that information. The Javadoc does not really help and I cannot find any complete examples of loading, querying, testing for errors, cataloging errors and so on.
This job is submitted via a NEWLINE_DELIMITIED_JSON record, supplied to the job via:
InputStream dummy = getClass().getResourceAsStream("/googlebigquery/xxx.record");
final InputStreamContent jsonIn = new InputStreamContent("application/octet-stream", dummy);
createTableJob = bigQuery.jobs().insert(projectId, loadJob, jsonIn).execute();
My authentication and so on seems to work correctly as separate Java code to list the projects, and the datasets in the project all works correctly. So I just need help in working what the actual error is - does it not like the schema (I have records nested within records for instance), or does it think that there is an error in the data I am submitting.
Thanks in advance for any help. The job number cited above is an actual failed load job if that helps any Google staffers who might read this.
It sounds like you have a couple of questions, so I'll try to address them all.
First, the way to get the status of the job that failed is to call jobs().get(jobId), which returns a job object that has an errorResult object that has the error that caused the job to fail (e.g. "too many errors"). The errorStream list is a lost of all of the errors on the job, which should tell you which lines hit errors.
Note if you have the job id, it may be easier to use bq to lookup the job -- you can run bq show <job_id> to get the job error information. If you add the --format=prettyjson it will print out all of the information in the job.
A hint you also might want to consider is to supply your own job id when you create the job -- then even if there is an error starting the job (i.e. the insert() call fails, perhaps due to a network error) you can look up the job to see what actually happened.
To tell BigQuery that some errors are allowed during import, you can use the maxBadResults setting in the load job. See https://developers.google.com/resources/api-libraries/documentation/bigquery/v2/java/latest/com/google/api/services/bigquery/model/JobConfigurationLoad.html#getMaxBadRecords().
