Binglin Chang commented on HDFS-6250:
-------------------------------------
I maded a patch to address this jira and HDFS-6159, along with a minor fix in
balancer.id ralated doc, changes:
1. make CAPACITY to 5000 rather than 6000, so it remains same ratio to block
size as before, make DEFAULT_BLOCK_SIZE useful
2. change validate method in testBalancerWithRackLocality so it doesn't depends
on balancer.id file
3. there is a doc error about balancer.id, fixed
With the change the test now runs only about 7 seconds, rather than 20+ seconds.
> TestBalancerWithNodeGroup.testBalancerWithRackLocality fails
