Event Server Index Upgrade Fails

In order to upgrade my CDH cluster from CDH4 to CDH5, I started with upgrading the Cloudera Manager to the latest version. The upgrade went through without any errors, but now the Event Server fails shortly after startup. I get the following error in the logs:

 

2014-08-19 10:55:49,813 INFO com.cloudera.cmf.eventcatcher.upgrade.IndexVersionManager: Creating IndexVersionManager for /var/lib/cloudera-scm-eventserver

java.lang.RuntimeException: Index Upgrade destination /var/lib/cloudera-scm-eventserver/v3 is not an empty directory. This likely means that the Event Server exited during a previous upgrade attempt. The Event Server will not start up until /var/lib/cloudera-scm-eventserver/v3 is removed, at which time the index upgrade will be retried.

2014-08-19 10:55:49,818 ERROR com.cloudera.cmf.eventcatcher.server.EventCatcherService: Could not ensure index is upgraded.

 

So it seems that some index upgrade is attempted but that fails. I also removed the directory, but after starting the Event Server again, the directory is created again and the service fails again. The size of the directory is always the same.

 

Any ideas how to fix this?

 

thanks and best regards
