Subject Need help in enabling debug logs for YARN daemons (Node Manager)
Date Sat, 16 May 2015 07:28:51 GMT
Not able to enable debug logs for yarn daemons or hdfs daemons.

Wants to enable debug level for all Node managers. So, tried the following,

   - changed Hadoop Root Logger to DEBUG,RFA (at HDFS -> Advanced
   hadoop-env)
   - hadoop.root.logger to DEBUG,console (at HDFS -> Advanced hdfs-log4j)
   - changed at YARN -> Advanced YARN env template

YARN_OPTS="$YARN_OPTS
-Dhadoop.root.logger=${YARN_ROOT_LOGGER:-DEBUG,console}"

YARN_OPTS="$YARN_OPTS -Dyarn.root.logger=${YARN_ROOT_LOGGER:-DEBUG,console}"




But nothing worked, even none of the processes log comes in debug level.
Even for HDFS (NN, DN) as well as YARN (RM, NM)

Env details :

Ambari version : 1.7
HDP 2.2
Debian 7

Please help in resolving this.

Thanks,
Chackra
