Thanks Michalis. I believe if I have to add this back to the cluster, those directories (of course based on configurations) would be created again.

Bump up. Sorry still confused about it.

Hi List, I have disk space limitation on couple of my datanodes (also have regionserver and nodemanager roles on them). It is on a public cloud, I already have the largest disk and they would not give me more disk. These machines are also running other high-priority processes (other than CDH processes), which needs disk space. So I want to free up space by taking hbase/hdfs off it and distribute the data to other nodes in the cluster. I have decommissioned the nodes and deleted the roles from the hosts but that does not free up /dfs directory on the hosts (still taking most of my disk space). Is it OK to directly delete the /dfs directory from the nodes, or make it empty? I want the flexibility of adding them back to the cluster at some point of time (may be once I have more disk), if I need to. I am hoping I am not the first one in this situation, any suggestions/work-arounds would be appreciated. Thanks, Akshay
