Description

The problem occurs when the cache has expired on server side and client want to resend it. This problem has been introduced in PHOENIX-4010. Actual result in this case is that client doesn't send the cache because of the following check:

			if (cache.addServer(tableRegionLocation) ... )) {
				success = addServerCache(table, startkeyOfRegion, pTable, cacheId, cache.getCachePtr(), cacheFactory, txState);
			}

Since the region location hasn't been changed, we actually don't send cache again, but produce new scanner which will fail with the same error and client will fall to recursion.
