Daniel Dai commented on HIVE-19810:
-----------------------------------
Unit test is tricky, seems tez container reuse properties are not controllable
in the client side. I don't want to touch MiniTezCluster setting to affect mass
tests. The attached testcase fails by chance in MiniTezCluster without the
patch. Similar test on single node cluster failed reliably for me.
> StorageHandler fail to ship jars in Tez intermittently

> Hive relies on StorageHandler to ship jars to backend automatically in
> several cases: JdbcStorageHandler, HBaseStorageHandler,
> AccumuloStorageHandler. This does not work reliably, in particular, the first
> dag in the session will have those jars, the second will not unless container
> is reused. In the later case, the containers allocated to first dag will be
> reused in the second dag so the container will have additional resources.
