Description

The RegionServer managers implement abort, close, and stop – although the interfaces are similar and all their meanings are muddled.

The conventions in hbase are gernally:
abort == passed into managers so they can trigger a suicide kill (for rs or hmaster)
stop == *managers for on the way to cleanup
cancel == operations that don't kill long running processes but bail out of the current attempt.
close == files or network resources.

This patch brings the naming into line.
