> 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 ...)]
