RE: Tables showing up as our_table-147a2090ed4211e480153bc81e542ebd/ in data dir

See https://github.com/apache/cassandra/blob/trunk/NEWS.txt#L173



SSTable data directory name is slightly changed. Each directory will have hex 
string appended after CF name, e.g. ks/cf-5be396077b811e3a3ab9dc4b9ac088d/

This hex string part represents unique ColumnFamily ID.

Note that existing directories are used as is, so only newly created 
directories after upgrade have new directory name format.

data dir


Using 2.1.4, tables in our data/ directory are showing up as



our_table-147a2090ed4211e480153bc81e542ebd/



instead of as



 our_table/



Why would that happen? We're also seeing lagging compactions and high cpu usage.



 Thanks, Don
