By default, you do not have write permission on the database /var/lib/cassandra/*. See step 4 in <a href="http://www.datastax.com/docs/1.2/install/install_bintar#steps-to-install-cassandra" rel="nofollow">http://www.datastax.com/docs/1.2/install/install_bintar#steps-to-install-cassandra</a>. </p> <p>I got the read and write to work using the example in the webinar (<a href="http://www.datastax.com/resources/webinars/collegecredit" rel="nofollow">http://www.datastax.com/resources/webinars/collegecredit</a>, see C*hristmas Comes Early at the bottom of the page). Used the latest Astyanax, and the pre-release version of the DataStax Java Driver. Please see post <a href="http://www.datastax.com/support-forums/topic/datastax-java-driver" rel="nofollow">http://www.datastax.com/support-forums/topic/datastax-java-driver</a> for some tips.</p> <p>I had to put everything on the localhost. </p> http://www.datastax.com/support-forums/topic/which-java-client-is-best-to-handle-cql3#post-8354 Thu, 10 Jan 2013 18:56:30 +0000 yingweiw 8354@http://www.datastax.com/support-forums/ <p>Astyanax dosen't work with Cassandra 1.2. I tried their examples: <a href="https://github.com/Netflix/astyanax/wiki/Cql-and-cql3" rel="nofollow">https://github.com/Netflix/astyanax/wiki/Cql-and-cql3</a>. Writing data dosen't work. Reading data works partially, I can read row out but parsing composite column fail.</p> <p>BTW, I'm using Astyanax version 1.56.21. </p> http://www.datastax.com/support-forums/topic/which-java-client-is-best-to-handle-cql3#post-8353 Thu, 10 Jan 2013 18:50:26 +0000 khahn 8353@http://www.datastax.com/support-forums/ <p>Great--here's a tip that I learned the hard way. When building the new Java driver for use with CQL 3 and Astyanax, I needed to skip the CCM tests by using execute: mvn install -Dmaven.test.skip=true. You can then add the jar in the driver-core/target directory to your eclipse project as shown in the C*hristmas Comes Early by Brian ONeill. </p> http://www.datastax.com/support-forums/topic/which-java-client-is-best-to-handle-cql3#post-8352 Thu, 10 Jan 2013 17:57:00 +0000 yingweiw 8352@http://www.datastax.com/support-forums/ <p>Thank you, guys. Trying Astyanax, will update my experience later. </p> http://www.datastax.com/support-forums/topic/which-java-client-is-best-to-handle-cql3#post-8336 Wed, 09 Jan 2013 01:02:10 +0000 thobbs 8336@http://www.datastax.com/support-forums/ <p>If you're feeling adventurous, there's also the new Java driver that uses the native binary protocol instead of being based on Thrift (like Hector and Astyanax): <a href="https://github.com/datastax/java-driver" rel="nofollow">https://github.com/datastax/java-driver</a> </p> http://www.datastax.com/support-forums/topic/which-java-client-is-best-to-handle-cql3#post-8335 Tue, 08 Jan 2013 23:51:50 +0000 khahn 8335@http://www.datastax.com/support-forums/ <p>I don't know, but in the webinar (<a href="http://www.datastax.com/resources/webinars/collegecredit" rel="nofollow">http://www.datastax.com/resources/webinars/collegecredit</a>, see C*hristmas Comes Early at the bottom of the page), the presenter said he preferred Astyanax. </p> http://www.datastax.com/support-forums/topic/which-java-client-is-best-to-handle-cql3#post-8333 Tue, 08 Jan 2013 18:50:35 +0000 yingweiw 8333@http://www.datastax.com/support-forums/ <p>New to Cassandra, I'm using the latest release 1.2, wondering which java client is best for CQL3? </p>
