--------------------------------------------

Thank you very much [~stack] for merging. 

I think we can ignore merge for branch-2.1 because Compaction_switch 
[HBASE-6028|https://issues.apache.org/jira/browse/HBASE-6028] is only available 
from branch-2.2.0.

> Compaction_switch does not work by RegionServer name

> Compaction_switch is used to stop running compaction on regionservers. This 
> switch works good by using "compaction_switch true/false" but rather I want 
> to stop compaction only for particular regionserver. In that case, the switch 
> doesn't work because serverName that we want to stop is not added into 
> CompletableFuture<List<ServerName>> [link| 
> [https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/client/RawAsyncHBaseAdmin.java#L3156]
>  ]. So we always get empty Future list by using RS name.
