Subject Cassandra 1.2.2 cluster + raspberry
Date Wed, 10 Apr 2013 00:54:54 GMT
Hi,

I'm trying to set up a cassandra cluster for some experiments on my
raspberry pies but I'm still having trouble to join my nodes to the cluster.

I started with two nodes (192.168.2.3 and 192.168.2.7) and when I start the
cassandra, I see the following exception on the node 192.168.2.7
ERROR [WRITE-/192.168.2.3] 2013-04-10 02:10:24,524 CassandraDaemon.java
(line 132) Exception in thread Thread[WRITE-/192.168.2.3,5,main]
java.lang.NoClassDefFoundError: Could not initialize class
org.xerial.snappy.Snappy

org.xerial.snappy.SnappyOutputStream.<init>(SnappyOutputStream.java:79)

I suspect that the lack of native snappy libraries are causing this
exception furing the internode communication.
I did not try to compile the native Snappy for ARM yet but I wonder if it
is not possible to use cassandra without snappy.

I've already tried to set internode_compression: none in my yaml files.

nodetool outputs:

nodetool -h pi1 ring
