I have Hadoop running on Standalone box. When I am starting deamon for namenode, secondarynamenode, job tracker, task tracker and data node, it is starting gracefully. But soon after it start job tracker it doesn't show up job tracker service. when i run 'jps' it is showing me all the services including task tracker except Job Tracker.
Is there any time limit that need to set up or is it going into the safe mode. Because when i saw job tracker log this what it is showing, looks like it is starting the namenode but soon after it shutdown: 2012-03-22 23:26:04,061 INFO org.apache.hadoop.mapred.JobTracker: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting JobTracker STARTUP_MSG: host = manish/10.131.18.119 STARTUP_MSG: args = [] STARTUP_MSG: version = 0.20.2-cdh3u3 STARTUP_MSG: build = file:///data/1/tmp/nightly_2012-02-16_09-46-24_3/hadoop-0.20-0.20.2+923.195-1~maverick -r 217a3767c48ad11d4632e19a22897677268c40c4; compiled by 'root' on Thu Feb 16 10:22:53 PST 2012 ************************************************************/ 2012-03-22 23:26:04,140 INFO org.apache.hadoop.security.token.delegation.AbstractDelegationTokenSecretManager: Updating the current master key for generating delegation tokens 2012-03-22 23:26:04,141 INFO org.apache.hadoop.security.token.delegation.AbstractDelegationTokenSecretManager: Starting expired delegation token remover thread, tokenRemoverScanInterval=60 min(s) 2012-03-22 23:26:04,141 INFO org.apache.hadoop.security.token.delegation.AbstractDelegationTokenSecretManager: Updating the current master key for generating delegation tokens 2012-03-22 23:26:04,142 INFO org.apache.hadoop.mapred.JobTracker: Scheduler configured with (memSizeForMapSlotOnJT, memSizeForReduceSlotOnJT, limitMaxMemForMapTasks, limitMaxMemForReduceTasks) (-1, -1, -1, -1) 2012-03-22 23:26:04,143 INFO org.apache.hadoop.util.HostsFileReader: Refreshing hosts (include/exclude) list 2012-03-22 23:26:04,186 INFO org.apache.hadoop.mapred.JobTracker: Starting jobtracker with owner as mapred 2012-03-22 23:26:04,201 INFO org.apache.hadoop.ipc.Server: Starting Socket Reader #1 for port 54311 2012-03-22 23:26:04,203 INFO org.apache.hadoop.ipc.metrics.RpcMetrics: Initializing RPC Metrics with hostName=JobTracker, port=54311 2012-03-22 23:26:04,206 INFO org.apache.hadoop.ipc.metrics.RpcDetailedMetrics: Initializing RPC Metrics with hostName=JobTracker, port=54311 2012-03-22 23:26:09,250 INFO org.mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog 2012-03-22 23:26:09,298 INFO org.apache.hadoop.http.HttpServer: Added global filtersafety (class=org.apache.hadoop.http.HttpServer$QuotingInputFilter) 2012-03-22 23:26:09,318 INFO org.apache.hadoop.http.HttpServer: Port returned by webServer.getConnectors()[0].getLocalPort() before open() is -1.
