Hi

I am currently evaluating Cassandra on a single node. Running the node seems fine, it responds to Thrift (via Hector) and CQL3 requests to create & delete keyspaces. I have not yet tested any data operations.

However, I get the following each time the node is started. This is using the latest production jars (v 1.2.1) downloaded from the Apache website:


 INFO [main] 2013-02-07 19:48:55,610 AutoSavingCache.java (line 139) reading saved cache C:\Cassandra\saved_caches\system-local-KeyCache-b.db

That binary file exists, though ofc the content is unreadable. Deleting the file and letting it be recreated doesn't help either.

Can anyone suggest any other solutions?

Cheers
