[jira] [Created] (HIVE-19810) StorageHandler fail to ship jars in Tez intermittently

---------------------------------

             Summary: StorageHandler fail to ship jars in Tez intermittently
                 Key: HIVE-19810
                 URL: https://issues.apache.org/jira/browse/HIVE-19810
             Project: Hive
          Issue Type: Bug
          Components: Tez
            Reporter: Daniel Dai
            Assignee: Daniel Dai


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.
