    • Changed log level of addition of blacklisted reason in the JobTracker log to debug instead of INFO

    Description

      Currently, when a TT is blacklisted by the node health check script, for every heartbeat a message such as the following is being logged.

      <date> <time> INFO org.apache.hadoop.mapred.JobTracker: Adding blacklisted reason for tracker : <blacklisted TT> Reason for blacklisting is : NODE_UNHEALTHY

      Due to this, the the JT logs fill up rapidly clogging the logdirs. Hence this message should be logged in DEBUG mode instead of INFO mode.
