We are using 5.8.0 version cluster. 2 days ago, we have encrypted our filesystem(GDE). Our cluster is hosted at IBM softlayer.
Our cloudera manager DB(sc,nav,navfs,..etc) is not embedded one, we are using mysql server separately.
Even that server has been encrypted. We have restarted the server after encryption. It was working fine for 4 hours. After the cloudera manager crashes, we are not able to get the GUI of the cloudera manager. We found that mysql service has been down. We make the services up with in an hour.
After restarting the mysql service, we are getting the GUI page as fresh installation, but we can see the currently managed hosts are still there.
But we are not able to pass any command related to hadoop, hbase etc.
Getting unrecognizable service error
Anyone can comment, why this is happening.?
Can we retrieve whole data in hdfs?
Please provide a solution
