Around 10 days back we upgraded our Cloudera manager from Cloudera manager 4.8.5 to Cloudera Express 5.5.1. This was working fine until today and in last few hours we seeing cloudera manager hanging till it is restarted. Our cluster is in CDH4. Also after upgrade of cloudera manager, we haven't restarted the cluster yet, this might not matter.
Has anybody faced similar issue?
