Is hadoop 1.x series deprecated now ?
Hi all,

As the version 2.2.0 is marked stable and is available for
general release, is version 1.x series deprecated now ?

As a Hadoop user, should I assume that the version 1.x series
is not going to be updated with newer updates e.g., newer
versions of HDFS. If that is going to be the case, can it be
marked as deprecated in the website.

Personally, I would have preferred the continuation of version 1.x series
due to its simplicity, as YARN tries to encompass things beyond
mapreduce and Hadoop has so far been about running
mapreduce jobs.

Also, is there any possibility that there would be
resource management features added to
the Hadoop 1.x series with its jobtracker/tasktracker model
(maybe backported from YARN) or
is the 1.x series not even considered for those types of features and
now has been completely abandoned.

Please excuse me if some of the points are not relevant or
important. I was just curious about the status of 1.x series as
I have been using it for quite a while now.
