-------------------------------
Summary: Remove the use of hard-coded cell size value in balancer
Dispatcher
Key: HDFS-8558
URL: https://issues.apache.org/jira/browse/HDFS-8558
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Kai Zheng
Fix For: HDFS-7285
This is part of work in HDFS-8494. To make it easy and discuss this case
better, open this issue to remove the use of hard-coded cell size value in
balancer Dispatcher separately. Also copied some good comments here:

It's easy to pass cellSize from BlockInfoStriped to Dispatcher. But the
question is BlockInfoStriped doesn't have it.
You have to get it by: BlockInfoStriped --> getBlockCollection --> getZone -->
getCellSize. A bit complicated, isn't it?
I think BlockInfoStriped needs to keep cellSize.

I too was thinking the same when the FSImageLoader problem has came up. This
will increase the memory usage by ~4bytes for each block though.
