Chen He commented on HDFS-6250:
-------------------------------
Thank you for your comments, [~decster].
I agree with you that the balancer.id file can bring more problems. There are
two ways to reduce the side-effect of the balancer.id file in this test method.
1) increasing the block size to reduce the impact of balancer.id file( this is
what I did);
2) introduce two new nodes, one in rack0 and one in rack1.
The failure in this JIRA is because of the balancer.id file's block (blk_181)
that should be deleted. We have to wait until that block is deleted. I created
a sub-task HDFS-6342 to redesign this test method.
