Review Comment:
Good point, can just check that class level variable.

> Issue Type: Sub-task
> Reporter: Rushabh Shah
> Assignee: Palash Chauhan
> Priority: Major
>
> Introduce a new RPC request from phoenix client to any region server via
> PhoenixRegionServerEndpoint#validateLastDDLTimestamp. Since the last ddl
> timestamp cache is maintained by all the regionservers, you can choose any
> regionserver randomly. In future, we can make this rpc more resilient by
> sending this rpc to multiple regionservers simultaneously.
> If phoenix client throws StaleMetadataCacheException then invalidate the
> cache on the client side and retry executeQuery method while fetching the
> updated metadata from SYSCAT regionserver.
