It retries multiple times until it finally fails and the repair session failed.
I tracked it down the problem to what I describe in the description by adding
multiple debug printouts in the streaming code.
> StreamReader fails to write sstable if CF directory is symlink

> Key: CASSANDRA-11978

> Project: Cassandra
> Issue Type: Bug
> Components: Streaming and Messaging
> Reporter: Michael Frisch
> Labels: lhf
>
> 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.
