https://community.cloudera.com/t5/Support-Questions/How-to-Sync-a-new-Secondary-Namenode-to-the-Cluster/m-p/192644#M154709 <P>I have 5 node cluster with 1 name node and 4 data nodes. Right now both my secondary name node and primary name node are on the same machine. I want to add a new secondary name node and sync it up with the rest of the hosts. </P><P>What is the best possible way to do this?</P><P>I tried using Ambari's "move secondary name node" wizard and it asked me to copy data into /hadoop/hdfs/namesecondary directory (which is on the boot disk with low disk space) in the new host. But I want to move it into the external hard disks I mounted on /mnt/data1-4. There are about 72 files in /hadoop/hdfs/namesecondary/current which I am not sure how to distribute into the /mnt disks. </P><P>Can some suggest what is the right way to do this?</P> Sat, 23 Sep 2017 07:31:30 GMT sree_kuppa 2017-09-23T07:31:30Z
