Worth also noting that 3.2 will not work without either this, or adding -R to the default flags (which is icky).

Same --user improvement as docker-library/rabbitmq#60; so OSX users can do the following and it should work.

$ docker run -d -v /Users/...cassandra/:/var/lib/cassandra --user 1000:50 cassandra

@yosifkit I like the idea, and now my container isn't crashing when i try to create a volume.
Unfortunately, it didn't solve my problem about sharing data volume. :/

Any idea ?

It seems that Cassandra uses memory mapped files like mongodb, and that is not possible in the virtual box shared folder. 😢

The only alternative is to setup nfs from host to vm.
