Standby checkpointing fails to authenticate in secure cluster
-------------------------------------------------------------
Key: HDFS-2924
URL: https://issues.apache.org/jira/browse/HDFS-2924
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, name-node, security
Affects Versions: HA branch (HDFS-1623)
Reporter: Todd Lipcon
Priority: Critical
When running HA on a secure cluster, the SBN checkpointing process doesn't seem
to pick up the keytab-based credentials for its RPC connection to the active. I
think we're just missing a doAs() in the right spot.
