> Each call for HTable.getStartEndKeys will read meta table.
> In particular,
> in the case of client side multi-threaded concurrency statistics,
> we must call HTable.coprocessorExec== > getStartKeysInRange ==>
> getStartEndKeys,
> resulting in the need to always scan the meta table.
> This is not necessary,
> we can implement the
> HConnectionManager.HConnectionImplementation.locateRegions(byte[] tableName)
> method,
> then, get the StartKeys and EndKeys from the cachedRegionLocations of
> HConnectionImplementation.
> Combined with https://issues.apache.org/jira/browse/HBASE-5491, can improve
> the performance of statistical
