Review request for hive, Gunther Hagleitner and Thejas Nair.
Bugs: HIVE-5246
https://issues.apache.org/jira/browse/HIVE-5246
Repository: hive-git
Description
-------
For a Hive query started by Oozie Hive action, the local task submitted for
Mapjoin fails. The HDFS delegation token is not shared properly with the child
JVM created for the local task.
Oozie creates a delegation token for the Hive action and sets env variable
HADOOP_TOKEN_FILE_LOCATION as well as mapreduce.job.credentials.binary config
property. However this doesn't get passed down to the child JVM which causes
the problem.
This patch is modifying HIVE-4343 to load the token file path from env variable
which will be set for both HiveServer2 (by original HIVE-4343 patch) as well as
Oozie.

Testing
-------
A test application attached to the ticket
(https://issues.apache.org/jira/secure/attachment/12602266/HIVE-5246-test.tar)
that simulates oozie behavior.
Manually tested HS2 to verify that it doesn't regress HIVE-4343
Thanks,
