Issuing the commands:</p> <p>cd /var/lib/cassandra<br /> chmod -R a+w *</p> <p>resolved the problem. </p> http://www.datastax.com/support-forums/topic/clients-get-connection-refused-when-datastax-enterprise-run-as-a-service#post-1928 Wed, 16 May 2012 23:39:05 +0000 Anonymous 1928@http://www.datastax.com/support-forums/ <p>I've installed DataStax Enterprise on RHEL 6.0 using the package install. If I start dse with the command:</p> <p>service dse start</p> <p>It starts correctly:</p> <blockquote><p> [root@bvdl-vm-01 opscenter]# service dse start<br /> Starting DSE daemon dse<br /> DSE daemon starting with Hadoop and Solr enabled (edit /etc/default/dse to disable) </p></blockquote> <p>However, if I attempt to connect to it, I get Connection Refused:</p> <blockquote><p> Starting Cassandra Client<br /> org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused: connect<br /> at org.apache.thrift.transport.TSocket.open(TSocket.java:183)<br /> at org.apache.thrift.transport.TFramedTransport.open(TFramedTransport.java:81)<br /> at org.apache.cassandra.cli.CliMain.connect(CliMain.java:79)<br /> at org.apache.cassandra.cli.CliMain.main(CliMain.java:255)<br /> Caused by: java.net.ConnectException: Connection refused: connect<br /> at java.net.PlainSocketImpl.socketConnect(Native Method)<br /> at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)<br /> at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195)<br /> at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182)<br /> at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)<br /> at java.net.Socket.connect(Socket.java:529)<br /> at org.apache.thrift.transport.TSocket.open(TSocket.java:178)<br /> ... 3 more<br /> Exception connecting to 138.42.81.221/9160. Reason: Connection refused: connect. </p></blockquote> <p>If I shut down the service and start dsn manually:</p> <p>dse cassandra</p> <p>then clients connect without any problem. Is there some additional configuration required to run as a service? </p>
