Hi, I enabled the "metrics.properties" to use FileContext, in which jvm metrics values are written to a file as follows:
jvm.metrics: hostName= localhost, processName=MAP, sessionId=, gcCount=10, gcTimeMillis=130, logError=0, logFatal=0, logInfo=21, logWarn=0, memHeapCommittedM=180.1211, memHeapUsedM=102.630875, memNonHeapCommittedM=23.191406, memNonHeapUsedM=11.828621, threadsBlocked=0, threadsNew=0, threadsRunnable=2, threadsTerminated=0, threadsTimedWaiting=3, threadsWaiting=2 Questions: - Is this line for a single Map jvm ? as the processName=MAP. If so, why doesn't it show job-id in sessionId ??? - Even though I ran maps and reducers tasks, I only got processName=MAP /SHUFFLE, nothing for reducers why? Thank you, Mark
