Hi,

We have couple of nodes in our cassandra cluster and the DSE version is 2.1.1-1. We down one of the node and start that node as hadoop enabled(changed the file /etc/default/dse).

Then we started that node by using the command (service dse start)
We got the message like, 'DSE started with hadoop enabled'. But the node looks down in the ring.

So we start the cassnadra service by using the command 'dse cassandra -t -j'(to enable jobtracker). But we are not able to start and the error message looks, 'The port is already used'.

Out intention is to run pig scripts on dse.

Is there anything we missed?

Thanks in advance.

To turn a node into an analytics node, please follow the instructions on http://www.datastax.com/docs/datastax_enterprise2.2/reference/start_stop_dse (see the Starting DataStax Enterprise as a Service section. You basically want to edit /etc/default/dse to set HADOOP_ENABLED=1. Note that you need to restart the service).

By running "dse cassandra -t -j" you are defacto trying to start a second instance (hence the port conflict).

Thanks,
Sven
