Yes it's a warning and not anything critical. Cassandra does start. The node operates and serves my website (all cassandra based). I'm just wondering if this is something I should consider correcting and wether it will impact the nodes performance.

Here's a listing of that file that it's complaining about being able to read:

-rw-r--r-- 1 root root 61 Jan 12 12:07 /var/lib/cassandra/saved_caches/system-schema_columnfamilies-KeyCache-b.db

Thanks,

Tim
