@Monalisa Tripathy

Is this what you are looking out for?

tez.am.log.level => Root logging level passed to the Tez Application Master.

yarn.app.mapreduce.am.log.level => The logging level for the MR ApplicationMaster. The allowed levels are: OFF, FATAL, ERROR, WARN, INFO, DEBUG, TRACE and ALL

The mentioned property should go inside mapred-site.xml.

Via Ambari UI --> MapReduce2 --> Configs --> Advanced --> "Advanced mapred-site". you will find a property by default set to INFO as following there you can change it to DEBUG:


yarn.app.mapreduce.am.log.level=INFO

.
