Few questions troubling me at moment with setup of Datastax Enterprise 2.2.2 are
Have started dse as service in Analytic mode. Below is the screen read.

a) Question is this analytic doesn't show up on opscenter screen.
b) dont have any files in /etc/dse/hadoop. I have purposefully deleted all. Now which is the default distributed file system port ? What would be the DFS folder structure ?
c) Is DFS using cassandraFS / HDFS ?
d) how can I make sure hadoop analytic node is up and running, ready for running a MR program.
