   Hi,
   I am attempting to start the server, but it fails with the following exception.

   Is this a new install? The compaction strategy(CFSCompactionStrategy) has been added in one of the later versions.

   It looks like you are trying to run DataStax Community which does not come with CFS support. That is only included in DataStax Enterprise.

   I was attempting to update existing Cassandra with the latest version when I ran into this problem. However, things worked fine once I deleted the contents of saved_caches, data and commitlog directory and restarted the server.

   Thanks,
   VS
