[jira] [Updated] (HADOOP-15121) Encounter NullPointerException when using DecayRpcScheduler

Jason Lowe updated HADOOP-15121:
Fix Version/s: 3.1.0
3.0.1
2.8.5
2.9.2
2.10.0
Thanks, [~Tao Jie]! I recently ran across this in 2.8 and saw it still wasn't
fixed in branch-2.8, so I committed this to branch-2, branch-2.9, and
branch-2.8. I also saw the Fix Version field in the JIRA wasn't set when this
was committed, so I updated that as well to reflect the 3.x versions.
