Phabricator commented on HIVE-2764:
-----------------------------------
enis has commented on the revision "HIVE-2764 [jira] Obtain delegation tokens
for MR jobs in secure hbase setup".
Some comments about the patch:
Changing the StorageHandler.configureJobProperties() to be called with the
actual job is kind of intrusive, so I have given up on that approach, and go
with the plan of obtaining the delegation tokens from the IF.getSplits() and
OF.checkOutputSpecs() time. However, one problem with this approach is that
although on the input side it works fine, on the output side, Hive does not use
OF's properly.
So, this patch adds a HiveOutputFormatImpl class, and changes the HOF to
extend OF. The actual usage of OFs are not changed as a part of this patch,
since it is out of the scope of this issue. However, not the HOFImpl class
delgates the checkOutputSpecs() call to the underlying OutputFormat, so that if
the OF wants to do any initialization, it can.
