Aman Preet Singh commented on OOZIE-751:
----------------------------------------
Yes. The cluster is set to run 100 Mappers and it has more than 60 map slots
free.
Yes, I am able to run sqoop commands in parallel from the command line. I tried
loading 6 tables in parallel and it runs fine.
Yes, I can see oozie:launcher and oozie:action (attachment

> Sqoop jobs through oozie hangs if I try to load more than 1 table in parallel

> 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.
