Maryann Xue resolved PHOENIX-2712.
----------------------------------
    Resolution: Not A Problem

I no longer use the PTableStats object in PTable now for getting the row count of a table (not a tablescan). Instead I get the stats for a table the same way I do for a tablescan.

>    Affects Versions: 4.7.0

> Looks like there are two problems:
> 1) When we do getTable(), we do not retrieve stats if tenantId != null.
> 2) When we do updateStatistics(), we clear cache based on the table's physical name. For multi-tenant view indexes, the physical table name is totally unrelated to the logical index table name. We need to do clearCache for the logical table name + tenantId as well.
> Not sure why, but my test cases used to pass without any fix to the second problem, but after my latest sync with master, they don't work any more unless I apply a fix for the second problem.
