Yuki Morishita commented on CASSANDRA-10006:
--------------------------------------------

This is from the change in CASSANDRA-7066.

I think we can just clean up tmps and tmplinks at the start up.

> In 3.0, {{Descriptor.fromFilename()}} doesn't handle "tmp" in sstable filenames in the 2.1 (ka) format.  If you start 3.0 with one of these filenames, you'll see an exception like the following:
> {noformat}
> ERROR [main] 2015-08-05 10:15:57,872 CassandraDaemon.java:623 - Exception encountered during startup

> I can reliably reproduce this with an [upgrade dtest|https://github.com/thobbs/cassandra-dtest/blob/8099-backwards-compat/upgrade_tests/cql_tests.py#L5126-L5162] from CASSANDRA-9704, but it should also be reproducible by simply starting 3.0 with a filename like the one from the error message.
