[jira] Created: (MAPREDUCE-732) node health check script should not
log "UNHEALTHY" status for every heartbeat in INFO mode
node health check script should not log "UNHEALTHY" status for every heartbeat in INFO mode
-------------------------------------------------------------------------------------------
Key: MAPREDUCE-732
URL: https://issues.apache.org/jira/browse/MAPREDUCE-732
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.21.0
Reporter: Ramya R
Priority: Minor
Fix For: 0.21.0
Currently, when a TT is blacklisted by the node health check script, for every heartbeat a message such as the following is being logged.
{noformat}
<date> <time> INFO org.apache.hadoop.mapred.JobTracker: Adding blacklisted reason for tracker : <blacklisted TT> Reason for blacklisting is : NODE_UNHEALTHY
{noformat}
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.
