Cloudera Manager Service Pause Duration issue

Cloudera Manager Service Pause Duration issue


Hi all,


We use for staging purpose Cloudera Enterprise Data Hub Edition Trial 5.4.3 with HBASE,HDFS,YARN and Zookeper.

There are 3 servers, one as master-namenode and two as datanodes.

We have the same environment on production site but with one master-namenode and six as datanodes.


On both environments we have the same error on the master-namenode and we lost the connection on GUI after while for a couple of seconds.


Pause Duration.

Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 1781ms: GC pool 'ConcurrentMarkSweep' had collection(s): count=1 time=2116ms

I think the problem is that I have to tune Java but I don't know exactly what value I have to change. 


Thanks in advance for your time.


Best regards,
