Using the CDH5 Virtualbox VM (cloudera-qs-vm-5.0.0-0) and Cloudera Manager is now failing to start

CM had been working but is now failing to start; appears to start but when I check status it shows as dead. The CM Web Admin Page shows the Loading message spinning with no resolution.


Starting via command line appears to work:


sudo service cloudera-scm-server start
Starting cloudera-scm-server: [ OK ]


But when I check status, server is dead:


[cloudera@localhost ~]$ sudo service --status-all | grep cloudera
cloudera-scm-agent (pid 9451) is running...
cloudera-scm-server dead but pid file exists


Stack trace in log (/var/log/cloudera-scm-server/cloudera-scm-server.log) shows:


2014-06-19 10:13:41,129 WARN [EventStorePublisherWithRetry-0:publish.EventStorePublisherWithRetry@195] Failed to publish event: SimpleEvent{attributes={CLUSTER_ID=[1], SEVERITY=[INFORMATIONAL], SERVICE=[ClouderaManager], COMMAND_ID=[789], COMMAND_RESULT=[Command 'Stop' failed for cluster 'Cloudera QuickStart - C5'], ALERT=[false], USER=[clouderaManager], MESSAGE_CODES=[COMMAND_FAILED_WITH_TARGET], CATEGORY=[AUDIT_EVENT], CLUSTER=[Cloudera QuickStart - C5], COMMAND_STATUS=[FAILED], COMMAND_ARGS=[RestartClusterCmdArgs{restartOnlyStaleServices=false, redeployClientConfig=false}], SERVICE_TYPE=[ManagerServer], COMMAND=[Restart], EVENTCODE=[EV_CLUSTER_RESTARTED]}, content=Command Restart on subject Cloudera QuickStart - C5 failed., timestamp=1403196216196} - 1 of 338 failure(s) in last 1804s Error connecting to unknown0800270ffe88:7184

So looks like it is attempting to connect to port 7184; this page shows that to be the Cloudera Manager Event Server:



Checking the port I see nothing is running on it:

sudo netstat -tulpn | grep 7184


Not sure if it is related but I installed Mongo on the box, 2.4 previously (and CM was working) and recently upgraded to 2.6.2 and then CM stopped working.

The posted log is an aside warning that deals with a management service not running. It is not the reason for the CM server failure. Please post the log here, or check it's near-the-crash/end of log for the actual failure reason.
