Subject [jira] [Commented] (HBASE-16945) Implement AsyncRegionLocator
Date Sat, 29 Oct 2016 14:57:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15618232#comment-15618232

stack commented on HBASE-16945:

The patch looks great.

There is little logging though on how region locator is working. I'd think a bunch of trace
level logging w/ detail on what it is doing would be good to have while it is new,. We'll
want to study how it is running out in the wild and to get detail on why it is stuck on a
cycle or continually returning a stale value. 

Otherwise, it is looking real nice.
