> 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.
