Sqoop jobs through oozie hangs if I try to load more than 1 table in parallel
-----------------------------------------------------------------------------
Key: OOZIE-751
URL: https://issues.apache.org/jira/browse/OOZIE-751
Project: Oozie
Issue Type: Bug
Affects Versions: 3.2.0
Environment: CentOs 5.0, hadoop-0.20.2, sqoop-1.3.0, oozie-2.3.2
Reporter: Aman Preet Singh
Attachments: how_3_oozie_jobs_look_in_jobtracker_ui.png, tasklog.htm,
workflow.xml
I want to load data from SQL Server to HDFS and am using the sqoop action of
Oozie as defined on page
http://archive.cloudera.com/cdh/3/oozie-2.3.2-cdh3u3/DG_SqoopActionExtension.html.
It works when I try to copy 1 table but when I try to copy more than 1 table is
parallel then the job just hangs. I don't see any errors anywhere in the logs.
- I have confirmed that there are no deadlocks on the database side.
- I have confirmed that if I try to load multiple table in parallel using sqoop
command line then it works fine
It looks like there is something in oozie sqoop action.
One more thing that I noticed is that there are 3 oozie jobs running in the
oozie console but 6 jobs are shown in Jobtracker UI (please see screenshot
attached). Not sure why that is.
The workflow.xml file, tasktracker logs for the task and how oozie directory
looks on HDFS is attached.
