             Summary: Hive on Tez job submission through WebHCat doesn't sh=
ip Tez artifacts
                 Key: HIVE-10066
                 URL: https://issues.apache.org/jira/browse/HIVE-10066
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


>From [~hitesh]:
Tez is a client-side only component ( no daemons, etc ) and therefore it is=
 meant to be installed on the gateway box ( or where its client libraries a=
re needed by any other services=E2=80=99 daemons). It does not have any clu=
ster dependencies both in terms of libraries/jars as well as configs. When =
it runs on a worker node, everything was pre-packaged and made available to=
 the worker node via the distributed cache via the client code. Hence, its =
client-side configs are also only needed on the same (client) node as where=
 it is installed. The only other install step needed is to have the tez tar=
ball be uploaded to HDFS and the config has an entry =E2=80=9Ctez.lib.uris=
=E2=80=9D which points to the HDFS path.=20


We need a way to pass client jars and tez-site.xml to the LaunchMapper.

We should create a general purpose mechanism here which would also include =
sending hive-site.xml to LaunchMapper so that there is no duplication betwe=
en hive-site.xml and templeton.hive.properties in webhcat-site.xml.
