[GitHub] zeppelin pull request #1979: [ZEPPELIN-2063] Hive Jdbc interpreter does not ...

    [ZEPPELIN-2063] Hive Jdbc interpreter does not relogin if kerberos ticket expired when hive.server2.transport.mode is http

    ### What is this PR for?
    Hadoop Client will re-login once the ticket expired in case of RPC and so when hive.server2.transport.mode is binary, Hive Jdbc interpreter does a relogin and works fine. But when Rest API is used i.e when hive.server2.transport.mode is http, it is not doing a re-login and so fails with GSS exception.
    
    ### What type of PR is it?
    [Bug Fix]
    
    
    ### What is the Jira issue?
    * [ZEPPELIN-2063](https://issues.apache.org/jira/browse/ZEPPELIN-2063)
    
    ### How should this be tested?
    Run hive in http mode i.e. hive.server2.transport.mode is http. Run any query say `show tables` now wait for key to expire (usually its 24hrs), now try to run the same paragraph again without restarting zeppelin-server or jdbc interpreter. It should not fail with `GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)
    ` exception
    
    ### Screenshots (if appropriate)
    N/A
    
    ### Questions:
    * Does the licenses files need update? N/A
    * Is there breaking changes for older versions? N/A
    * Does this needs documentation? N/A
