Hi I tried moving my data to a different directory (/data/hdfs/data) by adding the new directory to datanode dir in HDP configs and then copying the data, but I get this error:
2017-06-21 15:29:53,432 ERROR impl.FsDatasetImpl (FsDatasetImpl.java:activateVolume(398)) - Found duplicated storage UUID: DS-011fd6ee-105d-4c21-ba03-8f43bc75f0b2 in /data/hdfs/data/current/VERSION.

Should I just delete the original copied data files (/hadoop/hdfs/data)?
TIA!!
