RE: AsynchBase client holds stale dead region server for long time even after the META has already been update.

Thanks Shrijeet

Thanks for the information! We have seen this couple times recently. Last week, it was very long(like 40+ minutes before we restart). I will follow up on that discuss thread. Thanks a lot!!

This has been raised earlier
https://groups.google.com/d/topic/asynchbase/xE2lYE6CbmQ/discussion , https://groups.google.com/d/topic/asynchbase/nfLTwjdqq9M/discussion . It does look like a bug but a hard one to reproduce.

We have been seeing this it our production environment, efforts are on to reproduce this in testing environment.
