Sorry for the delay, [~enis], it seems I'm not receiving the notification on my primary mail

> In HBASE-10785, we removed the invalidation of the cached location from patch v2 to v3.
This results in a case where if there is a cached location for meta, it is not invalidated.

> Since we do a second check from cache for the location after acquiring the lock, this
results in metas location to be wrongly cached forever resulting in clients blocking indefinitely.
