Subject [jira] [Created] (HDFS-3447) StandbyException should not be logged at ERROR level on server
Date Sun, 20 May 2012 06:56:40 GMT
Todd Lipcon created HDFS-3447:

             Summary: StandbyException should not be logged at ERROR level on server
                 Key: HDFS-3447
                 URL: https://issues.apache.org/jira/browse/HDFS-3447
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: ha
    Affects Versions: 2.0.0
            Reporter: Todd Lipcon
            Priority: Minor

Currently, the standby NN will log StandbyExceptions at ERROR level any time a client tries
to connect to it. So, if the second NN in an HA pair is active, the first NN will spew a lot
of these errors in the log, as each client gets redirected to the proper NN. Instead, this
should be at INFO level, and should probably be logged in a less "scary" manner (eg "Received
READ request from client, but in Standby state. Redirecting client to other NameNode.")
