--------------------------------------
> coprocessor service requires .meta. to be available all the time.
> -----------------------------------------------------------------
>
> Key: HBASE-8136
> URL: https://issues.apache.org/jira/browse/HBASE-8136
> Project: HBase
> Issue Type: Bug
> Components: Client, Coprocessors
> Affects Versions: 0.95.2
> Reporter: Nicolas Liochon
> Priority: Minor
>
> HTable#getRegionLocations does not use a cache: all the calls to this
> function go to .META.
> So:
> - we're missing an opportunity to reuse/update the location cache in the
> HConnection.
> - this method is called by the coprocessor service. So, for people using this
> features, they have .meta. on their execution path, and it's not good for
> performances, scalability and reliability.
> I'm not totally clear on the fix. I think it should be possible to use the
> cache to see if we have all regions for the table. But it means we won't
> always have the last version when calling getRegionLocations.
> Any thought on this?
