-----------------------------------
Summary: TokenUtil.obtainToken squashes remote exceptions
Key: HBASE-17975
URL: https://issues.apache.org/jira/browse/HBASE-17975
Project: HBase
Issue Type: Bug
Components: security
Affects Versions: 2.0.0
Reporter: Sean Busbey
Assignee: Sean Busbey
Priority: Blocker
Fix For: 2.0.0
In the changes to protobuf handling in HBASE-15638, our TokenUtil class went
from handling remote exception via a method that would throw IOException to one
that simply returned it. In doing so, we ended up ignoring the results.
This causes the obtainToken method to start returning null where it would have
previously thrown an IOException. It also causes obtainTokenForJob to still
fail with an IOException, but instead of being the underlying remote problem
now it's a generic "I didn't get a user token for some reason."
found via testing Pig with errors.
