Hi,
After upgrading to Cassandra 1.1.0, I am facing some issue when starting
the Cassandra server.
This is the exception
[2012-04-27 19:31:38,740] INFO {org.apache.cassandra.db.Memtable} -
Writing Memtable-go@1431496612(656/820 serialized/live bytes, 12 ops)

This issue comes from snappy-java-1.0.4.1 library and it might be because
it uses a native library (libsnappyjava.so) and there are some issues when
it try to load that native library in osgi environment.
According to this [1] previously it didn't work with tomcat too. but they
have done some hack to get it work.
Does anybody know how to overcome this issue?
