The only error i could trace was in the nodemanager log file as below : ERROR org.apache.hadoop.yarn.server.nodemanager.NodeManager: RECEIVED SIGNAL 15: SIGTERM I tried checking various properties discussed in this thread, but i still have that issue. Can someone please help in solving this issue? Please let me know what all details i can provide.
