Check your VPC configuration and ensure "DNS resolution" is turned on. There's no need to restart the instances.

I should have mentioned earlier, HDFS Federation is not really supported in CDH5/CM5. Federation is from a time period where Namenode performance wasn't very scalable. Recent releases of Hadoop are quite good at scaling to many hundreds of nodes. Is there a reason you want to use Federation? Maybe we can resolve your problem another way.

GautamG · ‎06-15-2015

If HDFS Federation is involved, you can have up to two namenodes per namespace in a HA configuration. If your entire HDFS is using one namespace, then you can have up to Namenodes in the HA configuration.

The same parameter can be used to add other Java options, say to add GC logging. The list of options can be seen here: http://www.oracle.com/technetwork/articles/java/vmoptions-jsp-140102.html

Please edit the file /etc/default/cloudera-scm-server, the property is called CMF_JAVA_OPTS and the heap can be set with the -Xmx parameter

What version of Cloudera Manager are you running?

GautamG · ‎06-04-2015

I'll move this question to the right forum. Can you please post a screenshot of the issue and provide a more detailed description?

GautamG · ‎06-04-2015

On the node where the command is issues, can you please check if /etc/hadoop/conf/core-site.xml is present? Is this node marked as an HDFS Gateway? If so can you try redeploying client configuration across the cluster (dropdown action next to the cluster name in Cloudera Manager) and trying again?

Making a custom parcel is actually not that hard. You can follow the steps listed here: https://github.com/cloudera/cm_ext/wiki
