-----------------------------------
Assignee: Mingliang Liu
> Rebalancer sleeps too long between iterations
> ---------------------------------------------
>
> Key: HDFS-9761
> URL: https://issues.apache.org/jira/browse/HDFS-9761
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer & mover
> Reporter: Adrian Bridgett
> Assignee: Mingliang Liu
> Priority: Blocker
>
> Whilst reading the code to try and determine why I'm seeing bad performance I
> think I've spotted an inadvertent move of a sleep() to inside a for loop.
> This means that instead of sleeping once per iteration the balance is
> sleeping once per namenode per iteration. If I've done my maths correctly
> the sleep time default is 18seconds so this is a nice little speedup for HA
> clusters.
> Commit d31a41c35927f02f2fb40d19380b5df4bb2b6d57 moved the sleep in
> org/apache/hadoop/hdfs/server/balancer/Balancer.java:run()
