-------------------------------------
HI [~aw],
Thanks for your work on this. I have a question about running balancer as
daemon. User used to run the balancer at command line, and wait for it to
finish (it finishes when balancing criteria is satisfied). Now it can be run as
a daemon, does it mean the balancer daemon continues to monitor the HDFS state
and automatically start the balancing process when detecting that the balancing
criteria is not satisfied? thanks.
