Masahiro Tanaka updated AMBARI-21038:
-------------------------------------
Description:
When I tried to rebalance HDFS with Ambari, I pushed "Rebalance HDFS" in the
pulldown menu on each Hosts page.
I expected it worked same as I pushed "Rebalance HDFS" on Service Page, though
it doesn't work.
The error log is as below:
{code}
