I have couple of questions about HDFS federation:
Can I state different block store directories for each namespace on a
datanode ?
Can I have some datanodes dedicated to a particular namespace only ?
This seems quite interesting. Way to go !

Folks,
Its been an year and my HDFS / Solar /Hive setup is working flawless. The
data logs which were meaningless to my business all of a sudden became
precious to the extent that our management wants to backup this data. I am
talking about 20 TB of active HDFS data with an incremental of 2 TB/mon
; On disk, have another Hadoop cluster dans do regular distcp.

Team,
I am using Ambari to install a cluster which now needs to be deleted and
re-installed.
Is there a clean way to Uninstall the cluster, clean up all the binaries
from all the nodes and do a fresh install ?
There is no data on the cluster, so nothing to worry.
Thanks in advance
