[jira] [Created] (TEZ-349) Allow Tez sessions to be created in the TezClient

             Summary: Allow Tez sessions to be created in the TezClient
                 Key: TEZ-349
                 URL: https://issues.apache.org/jira/browse/TEZ-349
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth


Requested by [~hagleitn].

Essentially, users of TezClient (Hive in this case) would create a Tez session. This session can then be used to submit multiple DAGs. 

Internally, TezClient can control whether an AM is run within the same process, in unmanaged mode, on the cluster etc. Initially, we'd likely end up creating one AM per submitted DAG. Once TEZ-340 is in place, the same AM could be re-used for multiple non-concurrent DAGs.
