Jason Lowe commented on YARN-4924:
----------------------------------
Thanks for updating the patch!
If createWriteBatch does ever throw the runtime DBException we want that
translated to the IOException to avoid the exception bubbling up and becoming
fatal to the NM. Therefore the createWriteBatch call needs to be in the inner
try that will translate DBException->IOException. The sample code I wrote
above should cover the cases.
> NM recovery race can lead to container not cleaned up
