Hi Yogesh,

Just wanted to correct one point of yours:

In case you aren't aware yet, Hadoop (HDFS) has no single point of
failure anymore. The HDFS project implemented HA quite a while ago and
it works pretty well (and several of our customers run it too).

See http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/HDFSHighAvailability.html
for more. The release of 2.0.3, coming very soon, will also have a
non-NFS dependent form of HA support (trunk already has it).
