             Summary: LLAP: Invalid TEZ Job token in multi fragment query
                 Key: HIVE-24204
                 URL: https://issues.apache.org/jira/browse/HIVE-24204
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.3.0
            Reporter: Yuriy Baltovskyy
            Assignee: Yuriy Baltovskyy


When using LLAP server in the Kerberized environment and submitting the query 
via LLAP client that is planned as multi fragment (multiple splits), the 
following error occurs and the query fails:

org.apache.hadoop.ipc.Server: javax.security.sasl.SaslException: DIGEST-MD5: 
digest response format violation. Mismatched response.

This occurs because each split uses its own connection to LLAP server and its 
own TEZ job token while LLAP server stores only one token binding it to the 
whole query and not the separate fragment. When LLAP server communicates to the 
clients and uses the stored token, this causes Sasl exception due to using 
invalid token.
