> Trying to backport HBASE-22096 to brach-1, I faced the issue where a RS goes down with NPE when splitting a region with compaction disabled.
> The steps to reproduce this issue are as follows:
> {code}
> compaction_switch false
> create "test", "cf"
> (0...2000).each{|i| put "test", "row#{i}", "cf:col", "val#{i}"}
> split "test"
> {code}
> Looking at the regionserver log, I saw the following log:
> {code}
