> Abort the balancer if an upgrade is in progress
> -----------------------------------------------
>
> Key: HDFS-8549
> URL: https://issues.apache.org/jira/browse/HDFS-8549
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: balancer & mover
> Affects Versions: 2.7.0
> Reporter: Andrew Wang
> Assignee: Andrew Wang
> Attachments: HDFS-8549.001.patch, HDFS-8549.002.patch
>
>
> Running the balancer during an ongoing upgrade has a negative affect, since
> DNs do not actually delete blocks. This means the balancer is making lots of
> extra replicas and not actually reducing the disk utilization of
> over-utilized nodes.
