> Hive import fails upon re-run if Atlas Server was restarted after abnormal
> termination
> --------------------------------------------------------------------------------------
>
> Key: ATLAS-337
> URL: https://issues.apache.org/jira/browse/ATLAS-337
> Project: Atlas
> Issue Type: Bug
> Environment: Local
> Reporter: Hemanth Yamijala
>
> Atlas trunk
> HBase is configured as backing store for Titan (Version 1.1.2).
> Steps to reproduce:
> * Start the Atlas server
> * Start hive import using import-hive.sh
> * While still in progress, terminate Atlas server with a kill -9
> * Restart Atlas server.
> * Restart Hive import process.
> Expectation is that the Hive import goes through fine. However, it failed
> with exceptions indicating locks in HBase.
