Hi, I have installed the HDP 2.2 with Ambari 2.0.
I'm facing a big issue - I had kept the DataNode directories as : /nsr/hadoop/hdfs/data,/opt/hadoop/hdfs/data,/usr/hadoop/hdfs/data,/usr/local/hadoop/hdfs/data,/var/hadoop/hdfs/data Now, I want several disks to be mounted on each node and I want the ALL THE DATA BLOCKS TO BE STORED ON THESE DISKS. There is not much data on the HDFS and the same can be deleted. Is it possible now? Will only changing the DataNode directories help or any more paths need to be changed ? Regards, Omkar Joshi
