    <p>I've installed WS02 CEP (v2.1.0) and Datastax Community provided Apache Casandra (latest version) locally on my machine (Windows OS). I'm finding issues in launching them together probably because of clash of Thrift client port (9160). If I edit the cassandra.yaml file in the Datastax Community provided Cassandra folder and change the port to something else (say 9166), I can successfully launch both together. But then I cannot launch the cqlsh command based client to query Datastax Cassandra. It gives below error:</p> <pre><code>cql.cassandra.ttypes.InvalidRequestException: InvalidRequestException(why='Provided version 3.1.1 is not supported by this server (supported: 2.0.0, 3.0.0-beta1)') </code></pre> <p>I think the reason is that the cqlsh client is by default sending query to 9160 port. Now since I've edited the port, it is querying the Cassandra database embedded withing WSO2 CEP and that probably is of different version.</p> <p>I've now reverted the port back to 9160 in the cassandra.yaml file of the Datastax Community provided Cassandra folder. I'm now trying the other way; i.e., trying to edit port in the WSO2 CEP embedded Cassandra database. I edited the cassandra-component.xml file under C:\Program Files\wso2cep-2.1.0\repository\conf\etc and changed the port to 9166. However if I now launch both WSO2 CEP and Datastax Cassandra, I get the same error of port clash issue.</p> <pre><code>--------------------- java.lang.RuntimeException: Unable to create thrift socket to localhost/127.0.0.1:9160 at org.apache.cassandra.thrift.CassandraDaemon$ThriftServer.&lt;init&gt;(CassandraDaemon.java:147) at org.apache.cassandra.thrift.CassandraDaemon.startServer(CassandraDaemon.java:75) at org.apache.cassandra.service.AbstractCassandraDaemon.startRPCServer(AbstractCassandraDaemon.java:297) at org.apache.cassandra.service.AbstractCassandraDaemon.start(AbstractCassandraDaemon.java:269) at org.apache.cassandra.service.AbstractCassandraDaemon.activate(AbstractCassandraDaemon.java:366) at org.wso2.carbon.cassandra.server.CassandraServerController$1.run(CassandraServerController.java:48) at java.lang.Thread.run(Thread.java:724) Caused by: org.apache.thrift.transport.TTransportException: Could not create ServerSocket on address localhost/127.0.0.1:9160. at org.apache.cassandra.thrift.TCustomServerSocket.&lt;init&gt;(TCustomServerSocket.java:78) at org.apache.cassandra.thrift.CassandraDaemon$ThriftServer.&lt;init&gt;(CassandraDaemon.java:140) ... 6 more Exception encountered during startup: Unable to create thrift socket to localhost/127.0.0.1:9160 [2013-12-03 17:59:33,001] INFO {org.apache.cassandra.gms.Gossiper} - Announcing shutdown ----------------------------- </code></pre> <p>Can someone pls help out on how I can resolve this issue ? </p> <p>Many thanks in advance.</p> <p>Best Regards LB</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
