Hi All, We have hbase 0.94 running with 6 slave nodes. I need to change the dfs.data.dir (Data Node Storage Path) on two of the data nodes. What is the cleanest way to update the path. I googled and found two options 1. Remove the node from cluster (stop hbase region server, datanode, tasktracker) --> update the path in xml --> add the node to the cluster 2. Remove the node (stop hbase region server, datanode, tasktracker) -->Copy the data manually from old dfs.data.dir to the new dfs.data.dir --> Update the path in xml ---> add the node back to the cluster.
which is cleanest option of above two. Is there any disadvantage of any of the approach. -- View this message in context: http://apache-hbase.679495.n3.nabble.com/Need-to-update-dfs-data-dir-in-Data-Nodes-Best-approach-tp4051992.html Sent from the HBase User mailing list archive at Nabble.com.
