-----------------------------
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 ...)]
