ClassCastException during Cassandra server startup
Hello,
When I start the Cassandra server, some exceptions occur:

Thierry,
Key cache files are stored inside your saved_caches_directory defined in cassandra.yaml, which has default value of /var/lib/cassandra/saved_caches.

Hello Yuki,
Could you give me hints about where to find these files. I have a look
in the installation folder of Cassandra and in the /var/lib/cassandra
folder?
Thanks very much for your help.

That was bug in 1.1.1 and fixed in https://issues.apache.org/jira/browse/CASSANDRA-4331.
Workaround is deleting the key cache files for your index CFs should fix this.

Re: ClassCastException during Cassandra server startup

Hello,
My problem seems to occur after a server restart. As a matter of fact,
if I clean the data, create a new keyspace and and its structure with
cqlsh, I can use the database correctly (both with cqlsh and a Java
application with Astyanax). If I stop the server and restart it, I have
my problem and then my requests don't work anymore (for example,
requests with where clause).
Thanks for your help!
