AMBARI METRICS restart randomly

[#1]

Hi,

I built a new standalone hdp 2.3. This standalone are not yet sollicited by application but the ambari metrics service shutdown and restart for no reason. It can happen twice/three or four times a week.

This is the logs of my ambari-metrics-collector.log:

2016-03-14 01:29:07,166 ERROR org.apache.hadoop.yarn.server.applicationhistoryservice.ApplicationHistoryServer: RECEIVED SIGNAL 15: SIGTERM 2016-03-14 01:29:07,169 INFO org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation: Closing master protocol: MasterService 2016-03-14 01:29:07,182 INFO org.mortbay.log: Stopped HttpServer2$SelectChannelConnectorWithSafeStartup@0.0.0.0:6188 2016-03-14 01:29:07,207 INFO org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation: Closing zookeeper sessionid=0x1536be5998a0001 2016-03-14 01:29:07,208 INFO org.apache.zookeeper.ZooKeeper: Session: 0x1536be5998a0001 closed 2016-03-14 01:29:07,208 INFO org.apache.zookeeper.ClientCnxn: EventThread shut down 2016-03-14 01:29:07,286 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: Stopping phoenix metrics system... 2016-03-14 01:29:07,289 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: phoenix metrics system stopped. 2016-03-14 01:29:07,289 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: phoenix metrics system shutdown complete. 2016-03-14 01:29:07,290 INFO org.apache.hadoop.yarn.server.applicationhistoryservice.ApplicationHistoryManagerImpl: Stopping ApplicationHistory 2016-03-14 01:29:07,290 INFO org.apache.hadoop.ipc.Server: Stopping server on 60200 2016-03-14 01:29:07,294 INFO org.apache.hadoop.ipc.Server: Stopping IPC Server Responder 2016-03-14 01:29:07,294 INFO org.apache.hadoop.ipc.Server: Stopping IPC Server listener on 60200 2016-03-14 01:29:07,295 INFO org.apache.hadoop.yarn.server.applicationhistoryservice.ApplicationHistoryServer: SHUTDOWN_MSG:

Do you know the reason of this restarts?

Thanks,

What do you see in the AMS HBase logs? You will find them in the same directory as Ambari metrics collector logs.

Nothing interesting i think:

Can you share the Ambari Agent log on the Metrics collector host? That might give us some useful info.
