Two simple question about hadoop 2
Hi, all,
I have two simple questions about hadoop 2 (or YARN).
1. When will the stable version of hadoop 2.x come out?
2. We currently have a cluster deployed with hadoop 1.x, is there any way
to upgrade it to hadoop 2.x without damaging the existing data in current
HDFS?
Thank you very much!
Regards,
Yexi

No fixed date yet, but probably later this year. There is a formal
beta that should release soon (2.1.0-beta), which should evolve into a
stable version afterwards.

Upgrading to 2.x from 1.x is a supported scenario and does not harm
your HDFS data.
