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