If the nodetool shows the node, opscenter should show it as well.</p> <p>b)Default distributed file system is CassandraFS which is stored in C*, which should be found in /var/lib/cassandra/data or similar folder. check this link <a href="http://www.datastax.com/docs/datastax_enterprise2.2/solutions/about_hadoop#connecting-to-external-addresses" rel="nofollow">http://www.datastax.com/docs/datastax_enterprise2.2/solutions/about_hadoop#connecting-to-external-addresses</a></p> <p>c)CassandraFS</p> <p>d) follow the demo, e.g. <a href="http://www.datastax.com/docs/datastax_enterprise2.2/solutions/about_hive#hive-demo" rel="nofollow">http://www.datastax.com/docs/datastax_enterprise2.2/solutions/about_hive#hive-demo</a> </p> http://www.datastax.com/support-forums/topic/start-up-trouble-on-analytics#post-9169 Sun, 24 Feb 2013 21:36:39 +0000 bezgoan 9169@http://www.datastax.com/support-forums/ <p>Few questions troubling me at moment with setup of Datastax Enterprise 2.2.2 are<br /> Have started dse as service in Analytic mode.

I have purposefully deleted all. Now which is the default distributed file system port ? What would be the DFS folder structure ?</p> <p>c) Is DFS using cassandraFS / HDFS ?<br /> d) how can I make sure hadoop analytic node is up and running, ready for running a MR program.</p> <p>TIA<br /> Shashank. </p>
