-----------------------------------
Resolution: Fixed
> Explain Plan should output region locations with servers
> --------------------------------------------------------

> Key: PHOENIX-6907
> URL: https://issues.apache.org/jira/browse/PHOENIX-6907
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Fix For: 5.2.0, 5.1.4
>
>
> As of today, explain plan provides details related to scan key range size,
> size of the scan lists (for parallel scans), hints, client/server sorted by,
> order by, server filter etc. It provides as much close details to the
> physical plans as possible.
> If we could also make explain plan output to include region locations that
> also contains regionserver details on which the region is currently residing,
> this might turn out to be really good insights. For full table scans, this
> also means that we would end up including very higher number of region
> locations and it would not be ideal to print all of them in the output. We
> can enforce a limit on the num of region locations to print (default value
> could be 10 or so). For point lookup and range scans, we can find the region
> locations with regionserver as quite useful for the real time analysis of
> slowness experienced by the given query.
