On HDP 2.3.4, using Oozie 4.2.0 and Sqoop 1.4.2, I'm trying to create a coordinator app that will execute sqoop jobs on a daily basis. I need the sqoop action to execute jobs because these are incremental imports.
I've configured `sqoop-site.xml` and started the `sqoop-metastore` and I'm able to create, list, and delete jobs via the command line but the workflow encounters the error: Cannot restore job: streamsummary_incremental
stderr
Sqoop command arguments :
job
--exec
streamsummary_incremental

Additional info:
- We're only running a single-node cluster.
- Only Sqoop Client is
installed.
I'm thinking maybe Oozie isn't able to connect to the metastore because we don't have sqoop server? Could anyone confirm this? If not that, could I have missed anything else?
Thanks!
