             Summary: StreamReader fails to write sstable if CF directory is 
symlink
                 Key: CASSANDRA-11978
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11978
             Project: Cassandra
          Issue Type: Bug
          Components: Streaming and Messaging
            Reporter: Michael Frisch


I'm using Cassandra v2.2.6.  If the CF is stored as a symlink in the keyspace 
directory on disk then StreamReader.createWriter fails because 
Descriptor.fromFilename is passed the actual path on disk instead of path with 
the symlink.

Example:
/path/to/data/dir/Keyspace/CFName -> /path/to/data/dir/AnotherDisk/CFName

Descriptor.fromFilename is passed "/path/to/data/dir/AnotherDisk/CFName" 
instead of "/path/to/data/dir/Keyspace/CFName", then it concludes that the 
keyspace name is "AnotherDisk" which is erroneous. I've temporarily worked 
around this by using cfs.keyspace.getName() to get the keyspace name and 
cfs.name to get the CF name as those are correct.
