Subject [jira] [Created] (HIVE-17648) Delegation token can't be passed through from Hive to HBase when required by UDF
Date Fri, 29 Sep 2017 01:40:00 GMT
iBenny created HIVE-17648:
-----------------------------

             Summary: Delegation token can't be passed through from Hive to HBase when required
by UDF
                 Key: HIVE-17648
                 URL: https://issues.apache.org/jira/browse/HIVE-17648
             Project: Hive
          Issue Type: Improvement
          Components: CLI
    Affects Versions: 1.1.1
            Reporter: iBenny


When using Hive CLI to query a Hive table with UDF which needs to access HBase with Kerberos,
 the delegation token can't be passed through to HBase from Hive CLI. Usually, if we access
a Hbase directly from Hive CLI, Hive CLI will get the delegation token before the job starting.  But
in this case hive CLI don't know this job need a HBase delegation token until the UDF was
running in the map task and then error happened in the map job:
GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level:
Failed to find any Kerberos ...)]
