Hello, Today RM crashed and I am trying to find what caused this. This is what I found in cloudera-scm-agent log: [13/Oct/2017 17:07:47 +0000] 2807 MainThread agent INFO PID '8311' associated with process '1209-yarn-RESOURCEMANAGER' with payload 'processname:1209-yarn-RESOURCEMANAGER groupname:1209-yarn-RESOURCEMANAGER from_state:RUNNING expected:0 pid:8311' exited unexpectedly In hadoop-yarn-resourcemanager log these are last entries before crash: 2017-10-13 17:06:33,271 WARN org.apache.hadoop.yarn.server.resourcemanager.rmapp.RMAppImpl: The specific max attempts: 0 for application: 5188 is invalid, because it is out of the range [1, 2].

Also, RM restarted without issues. Thanks.
