I was running into troubles today while running Airflow and airflow-dbt-python. I tried to debug a bit using the logs and the error shown in the logs was this one:
[2022-12-27, 13:53:53 CET] {functions.py:226} ERROR - [0m12:53:53.642186 [error] [MainThread]: Encountered an error:
Database Error
Expecting value: line 2 column 5 (char 5)
Quite a weird one.
Possibly check your credentials file that allows DBT to run queries on your DB (in our case we run DBT with BigQuery), in our case the credentials file was empty. We even tried to run DBT directly in the worker instead of running it through airflow, giving as a result exactly the same error. Unfortunately this error is not really explicit.

I am executing dbt run -s model_name on CLI and the task completes successfully. However, when I run the exact same command on dbt cloud, I get this error:
Syntax or semantic analysis error thrown in server while executing query.
Error message from server: org.apache.hive.service.cli.HiveSQLException:
Error running query: org.apache.spark.sql.AnalysisException: cannot
resolve '`pv.meta.uuid`' given input columns: []; line 6 pos 4;
\n'Project ['pv.meta.uuid AS page_view_uuid#249595,
'pv.user.visitorCookieId AS (80) (SQLExecDirectW)")
it looks like it fails recognizing 'pv.meta.uuid' syntax which extract data from a json format. It is not clear to me what is going on. Any thoughts? Thank you!
I'm using Hue for PIG scripts on amazon EMR. I am using the declare and default statements as mentioned in the documentation.
I have some %default and %declare statements and it looks like they are
not preprocessed within Hue. Therefore, although the parameters are defined
in my script, the editor keeps popping in a parameter configuration window. If I leave the parameter blank, the job fails with an error.
Sample Script
%declare OUTPUT_FOLDER 'testingOutput01';
ts = LOAD 's3://testbucket1/input/testdata-00000.gz' USING PigStorage('\t');
STORE ts INTO 's3://testbucket1/$OUTPUT_FOLDER' USING PigStorage('\t');
Upon execution, it shows the pop-up window asking for values for OUTPUT_FOLDER. If I leave it blank it fails with the following error:
2015-06-23 20:15:54,908 [main] ERROR org.apache.pig.Main - ERROR 2997:
Encountered IOException. org.apache.pig.tools.parameters.ParseException:
Encountered "<EOF>" at line 1, column 12.
Was expecting one of:
<IDENTIFIER> ...
<OTHER> ...
<LITERAL> ...
<SHELLCMD> ...
Is that the expected behavior? Is this a known issue or am I missing something?
Configuration details:
AMI version:3.7.0
Hadoop distribution:Amazon 2.4.0
Applications:Hive 0.13.1, Pig 0.12.0, Impala 1.2.4, Hue
The same behavior is seen with default instead of declare.
If you need any clarifications then please do comment on this question. I will update it as needed.
Hue does not support %declare with a default statement. It will be fixed with: https://issues.cloudera.org/browse/HUE-2508
The current temporary workaround is to put any value in the popup.
when i am trying to show tables from hive databases the following error displays..
i granted permissions to ware house & Tables even though the error shows
hive> show tables;
FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
Thanks in advance.
this error occurs when hive CLI is terminated improperly.
solution:
exit from hive, give 'jps' command. some process named runjar will be there. kill it using ' kill -9 pid'
thats it. you are done.
plz ignore typo- replied from mobile

Could anyone help me to interpret this?
I had the same problem.
My fix:
There needs to be an entry in the database change log lock table; it needs to have id=1, locked=false and the rest of the values set to null.
I'm getting the same error also using MySQL and tried v3.0.0 and 3.0.5 of liquibase. The error was the same when I tried to do a migrate as well as a generateChangeLog.
./liquibase --logLevel=debug --changeLogFile=./db.changelog-test-v0.1.xml --username=abc --password=abc99 --url="jdbc:mysql://localhost:3306/test" migrate
FYI, here is the select statement that it had trouble executing for the 'migrate' command:
select view_definition from information_schema.views where table_name='patient_info' and table_schema='test'
The information_schema.views table is empty.
I am using ssis of sql 2008 trying to connect to sybase 12 using sybase 15.2 driver, i even tried sybase 12 driver and got same error
error message
[ZZZZZ]

[ASEOLEDB]Stored procedure 'sp_oledb_datatype_info' not found.
Specify owner.objectname or use sp_help to check whether the object exists (sp_help may produce lots of output). (ASEOLEDB)
attached images showing that i am able to connect but soon after connecting i get the error message
Step 1
Step 2
Error message when i used ADO.NET
Look like you have to investigate more about this problem and by reading in the SyBooks Online it say:
If error 2812 occurs on system stored procedures (as your case sp_oledb_tables and sp_oledb_datatype_info) it may be resolved by running the installmaster script, which installs all system procedures and initializes various other Adaptive Server structures.
How to run the installmaster script?
Using isql, run the new installmaster script included with this release by entering:
isql -Usa -P<sa password> -S<server name> -n -i$SYBASE/$SYBASE_ASE/scripts/installmaster
-o<output file>

Hope it help you
