Hi all, Spark streaming program will connect Hbase and ES to do some data verification realtime. But my spark application always crash after one or two days. And I got the following error. Can anybody tell me how to identify the reason ? Thanks a lot. 16/12/18 19:08:24 ERROR executor.CoarseGrainedExecutorBackend: RECEIVED SIGNAL 15: SIGTERM 16/12/18 19:08:24 INFO common.GlobalHConnection: Closing the global HBase connection 16/12/18 19:08:24 INFO client.ConnectionManager$HConnectionImplementation: Closing zookeeper sessionid=0x458860dc3ec19c5 16/12/18 19:08:24 INFO storage.DiskBlockManager: Shutdown hook called 16/12/18 19:08:24 INFO zookeeper.ZooKeeper: Session: 0x458860dc3ec19c5 closed 16/12/18 19:08:24 INFO zookeeper.ClientCnxn: EventThread shut down 16/12/18 19:08:24 INFO common.GlobalHConnection: The global HBase connection closed ----------------------------- Best Regards ...
