Subject [jira] [Created] (HBASE-14276) NPE when setting up stub for connection to master if secure connect is refused
Date Thu, 20 Aug 2015 21:11:45 GMT

--------------------------------------

             Summary: NPE when setting up stub for connection to master if secure connect
is refused
                 Key: HBASE-14276
                 URL: https://issues.apache.org/jira/browse/HBASE-14276
             Project: HBase
          Issue Type: Bug
            Reporter: Andrew Purtell
            Priority: Minor
             Fix For: 0.98.15


If an insecure client contacts a secure cluster we can get an NPE when setting up the stub
for the master connection. This can happen if auth tokens are not passed correctly to a mapreduce
job and obscures the true cause. We should throw an IOException with a clear message, and
not retry if possible to distinguish this case.

Found in 0.98 but might be relevant for later branches
