I am trying to import table from mysql to hive then i am getting following error.
can you please provide the solution for this.
bin/sqoop import --connect jdbc:mysql://202.63.155.22:3306/demo --username careuser --P --table caremanager --hive-import --verbose -m 1
3/12/30 02:42:05 WARN hive.TableDefWriter:

Actually sqoop is trying to access hive for creating hive table but cant execute it. Is hive installed on your machine and is Hive home is set in PATH environment variable.Please verify it.Hope these will solve your problem.

I am trying to sqoop hive view to SQL server database however i'm getting "object not found error". Does sqoop export works for hive views?
sqoop export --connect 'jdbc:jtds:sqlserver:<Connection String>' --table 'tax_vw' --hcatalog-database default --hcatalog-table tax_vw --connection-manager org.apache.sqoop.manager.SQLServerManager --driver net.sourceforge.jtds.jdbc.Driver --username XXX --password YYY --update-mode allowinsert
INFO hive.metastore: Connected to metastore. ERROR tool.ExportTool:
Encountered IOException running export job: java.io.IOException:
NoSuchObjectException(message:default.tax_vw table not found)
Need help on this.
Unfortunately, this is not possible to do using sqoop export, even if --hcatalog-table specified, it works only with tables and if not in HCatalog mode, it supports only exporting from directories, also no queries are supported in sqoop-export.
You can load your view data into table:
create table tax_table as select * from default.tax_vw;
And use --hcatalog-table tax_table
I am getting below error while importing data from oracle DB to HIVE using Sqoop
ERROR tool.ImportTool: Encountered IOException running import job: java.io.IOException: Cannot run program "hive": error=2, No such file or directory
below is my command which I am executing.
sqoop import --connect jdbc:oracle:thin:#host:port/xe--username sa -- password sa --table SA.SHIVAMSAMPLE --hive-import -m 1
The data is getting created inside hdfs but hive tables are not getting created i.e a folder gets created inside (bin/hdfs dfs -ls) direct default directory.
when I will give explicitly path for warehouse then only it will store in warehouse directory like "user/hive/warehouse" after that also table not created and not loaded data.
I installed hadoop in "Amit/hadoop-2.6.5" and HIVe is "Amit/apache-hive-1.2.1-bin" and sqoop "Amit/sqoop-1.4.5-cdh5.3.2" in .bashrc I set the hadoop path only.
Is require to hive and sqoop as well.
When I set hive home in sqoop-env.sh file then above command run fine but table is not created and file is created inside hdfs /user/hive/warehouse/shivamsample
can you please tell me any extra conf require to resolve this issue.
I am using sqoop to copy a Postgres table to s3 using the following command
sqoop import -m 1 --connect jdbc:postgresql://xx.us-west-2.rds.amazonaws.com:5432/prod_db --username user_ro --password user_pwd --table content --target-dir s3://test/user/sqoop_test --as-avrodatafile
This works for the first time. Before the next execution I deleted the target directory using:
aws s3 rm s3://test/user/sqoop_test
Next execution of sqoop results in following error:
18/07/21 05:31:53 ERROR tool.ImportTool: Encountered IOException running import job: com.amazon.ws.emr.hadoop.fs.consistency.exception.ConsistencyException: Directory 'user/sqoop_test' present in the metadata but not s3

at com.amazon.ws.emr.hadoop.fs.consistency.ConsistencyCheckerS3FileSystem.getFileStatus(ConsistencyCheckerS3FileSystem.java:380)
I have also tried doing "emrfs delete..." followed by "emrfs import..." & "emrfs sync.." But that didn't help resolve the problem. Any help will be appreciated.
Im using the below command for importing data from sqlserver to Azure blob storage
sqoop import -Dorg.apache.sqoop.splitter.allow_text_splitter=true --connect "jdbc:sqlserver://server-IP;database=database_name;username=user;password=password"
--username test --password "password" --query "select top 5 * from employ where \$CONDITIONS" --delete-target-dir --target-dir 'wasb://sample#workingclusterblob.blob.core.windows.net/source/employ'
-m 1
getting below error
18/01/30 03:35:45 INFO tool.ImportTool: Destination directory wasb://sample#workingclusterblob.blob.core.windows.net/source/employ is not present, hence not deleting.
18/01/30 03:35:45 INFO mapreduce.ImportJobBase: Beginning query import.

Logs statement are confusing which tells both as not present for deleting and present while writing.
From Apache Sqoop user guide:
By default, imports go to a new target location. If the destination
directory already exists in HDFS, Sqoop will refuse to import and
overwrite that directory’s contents. If you use the --append argument,
Sqoop will import data to a temporary directory and then rename the
files into the normal target directory in a manner that does not
conflict with existing filenames in that directory.
I'm not in the Azure environment to reproduce and validate the solution, But Try adding the --append to your sqoop import and let me know.
sqoop import -Dorg.apache.sqoop.splitter.allow_text_splitter=true --connect "jdbc:sqlserver://server-IP;database=database_name;username=user;password=password"
--username test --password "password" --query "select top 5 * from employ where \$CONDITIONS" --delete-target-dir --append --target-dir 'wasb://sample#workingclusterblob.blob.core.windows.net/source/employ'

I have successfully installed and data imported from MySql to the HDFS but I couldn't get the
data in the Hive. the corresponding data imported from the Mysql is found in Hdfs as comma separated format.
Older versions of sqoop using
sqoop import --connect jdbc:mysql://remote-ip/db --username xxx --password xxx --table tb --hive-import --hive-table foo.tb
In Sqoop2 i couldn't find an option to set the hive table options while creating the job or connectors
Please help...
Sqoop2 currently do not have integration with Hive and can import data only to HDFS. You can load them into Hive manually from there though (using LOAD DATA command). Or you can continue using Sqoop1 for the time being.
