[jira] [Created] (YARN-5365) Add support for YARN Shared Cache

Ming Ma created YARN-5365:
-----------------------------

             Summary: Add support for YARN Shared Cache
                 Key: YARN-5365
                 URL: https://issues.apache.org/jira/browse/YARN-5365
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Ming Ma


YARN provides shared cache in functionality YARN-1492. According to [~ctrezzo] most of the YARN functionality is in hadoop 2.8 and frameworks can start to use it. MR adds the support via MAPREDUCE-5951.

Can anyone confirm if Tez supports the upload of application DAG jar and dependent lib jars from client machine to HDFS as part of Tez app submission? From my test, that doesn't seem to happen. Tez expects applications to upload the jars to HDFS beforehand and then set the tez.aux.uris to the HDFS locations.
