---------------------------------
Summary: Log namenode hostname in various exceptions being thrown
in a HA setup
Key: HDFS-5653
URL: https://issues.apache.org/jira/browse/HDFS-5653
Project: Hadoop HDFS
Issue Type: Improvement
Components: ha
Affects Versions: 2.2.0
Reporter: Arpit Gupta
In a HA setup any time we see an exception such as safemode or namenode in
standby etc we dont know which namenode it came from. The user has to go to the
logs of the namenode and determine which one was active and/or standby around
the same time.
I think it would help with debugging if any such exceptions could include the
namenode hostname so the user could know exactly which namenode served the
request.
