Chen He commented on HDFS-7639:
-------------------------------
Hi [~szetszwo], I am little bit confused about this JIRA. In HDFS-6595,
maximium threads limits were added to avoid balancer overwhelm the datanode. If
I am right, do you mean, we weaken the limits and make them non-blocking?
> Remove the limitation imposed by dfs.balancer.moverThreads

> Key: HDFS-7639
> URL: https://issues.apache.org/jira/browse/HDFS-7639
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: balancer & mover
> Reporter: Tsz Wo Nicholas Sze
> Assignee: Chen He
>
> In Balancer/Mover, the number of dispatcher threads
> (dfs.balancer.moverThreads) limits the number of concurrent moves. Each
> dispatcher thread sends request to a datanode and then is blocked for waiting
> the response. We should remove such limitation.
