Hi, This is the current setup.


2 node cluster


Dell servers same specs


128gb mem

3.4tb hdd

RHEL subscription


The current setup is really from a 3 node cluster, down to 2 node (some license problems) by using the forget node button on the MCS. I already run the -R, -C node1:7222,node2:7222 and -Z node1:5181,node2:5181.

Also I fail to create a remote mirror and I assume its because of this node manager is down.

this is the error Volume Creation Failed 


I also attached the /opt/mapr/hadoop/hadoop-2.7.0/logs for node manager logs

Also attached the warden logs.


I already run out of ideas on how to resolve this, after I removed the 3rd node the cluster is technical messed up.
