> Fix HDFS Balancer to honor upgrade domain policy
> ------------------------------------------------
>
> Key: HDFS-9007
> URL: https://issues.apache.org/jira/browse/HDFS-9007
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Ming Ma
> Assignee: Ming Ma
> Attachments: HDFS-9007.patch
>
>
> In the current design of HDFS Balancer, it doesn't use BlockPlacementPolicy
> used by namenode runtime. Instead, it has somewhat redundant code to make
> sure block allocation conforms with the rack policy.
> When namenode uses upgrade domain based policy, we need to make sure that
> HDFS balancer doesn't move blocks in a way that could violate upgrade domain
> block placement policy.
> In the longer term, we should consider how to make Balancer independent of
> the actual BlockPlacementPolicy as in HDFS-1431.
