Walter Su updated HDFS-8558:
----------------------------
Parent Issue: HDFS-8031 (was: HDFS-7285)
> 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
> Assignee: Walter Su
> 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:
> From [~walter.k.su]:
> {quote}
> 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.

> From [~vinayrpet]:
> {quote}
> 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.
