Subject Re: java.io.FileNotFoundException when setting up internode_compression
Date Thu, 14 Nov 2013 02:01:00 GMT
IIRC there is a test for snappy when the node starts does that log an error ? 

And / or can you create a CF that uses snappy compression (it was the default for a while
in 1.2). 

Cheers

is not there, permissions look ok, are there any special settings (like JVM args) that I should
be using ? I can see libsnappyjava.so in the jar though (snappy-java-1.0.5.jar\org\xerial\snappy\native\Linux\i386\)
one other thing I am using RedHat 6. I will try updating glibc ans see what happens.

= all to work. I am getting  the following exception. I am using cassandra 1.2.9 and have
snappy-java-1.0.5.jar in my classpath. Google search did not return any useful result, has
anyone seen this before ?
