How to rebalance individual directory

How to rebalance individual directory

Rising Star

hi dear experts!


i do have rebalanced (across DataNodes) HDFS directory.

it's not so big in Cluster scale (lile 1TB), so global rebalancer donesn't move this blocks (note: i use to check distribution).

i could perform:

hadoop fs -mv /dir /dir2

hadoop fs -cp /dir2 /dir

hadoop fs -rm dir2


and it helps.


but does anyone knows more elegant and sophisticated solution?
