Subject [jira] Resolved: (HBASE-723) TableServers's cachedRegionLocation doesn't have size limit.

Andrew Purtell resolved HBASE-723.

    Resolution: Won't Fix

For this specific issue a limit on TableServers cachedRegionLocation as stack says is probably
not necessary because a soft map is used.

> cachedRegionLocation stores region locations of tables whenever new region is looked
up. However, the enties are deleted only when TableServers object is closed or locateRegion
is called with false useCache argument. Therefore, it seems to grow without limit and cause
out of memory exception.
