Is "/usr/share/cassandra/data" a local drive, or NFS? Anyone doing any changes 
to fstab / mounted volumes?

Strange Cassandra startup error

[William Boutin]

I've been running apache-cassandra 2.2.6 for a few years. Recently when I 
configured a new cassandra node and started Cassandra via "service start 
cassandra" on LINUX 6.5, I got the following exception. After cleaning out my 
data_file_directories I was able to successfully restart. Any ideas? Thanks
