Hi all, I have 6 datanodes on my hortonworks cluster (HDP 2.6.3) and one of them is 91% full. The others are "only" 65% full. Il don't understand why the replication is not homogeneous and how i can fix it ? I check the file system and the same difference is observed : On a safe node : # pwd /grid1/hadoop/hdfs/data/current/BP-332877091-10.136.82.11-1500650625087/current/finalized # du -h . --summarize 1.9T    . On the unsafe node : # pwd /grid1/hadoop/hdfs/data/current/BP-332877091-10.136.82.11-1500650625087/current/finalized # du -h . --summarize 2.7T    . Same things on each DataNode directories.
