Hi,   I am trying to move all the master node services to a new host and decommission the old node. I am able to do few of the services through Ambari UI by using move option under service actions.

Hi, In my HDP cluster the Data Directory on one particular Data Node is almost Full (98%), while other data node data directories are below 60%. How can I know why HDFS is writing data into that one particular Data Node. I am worried if this might effect the cluster performance and would like to know how can I distribute the data to different data nodes.
