Brandon Williams commented on CASSANDRA-7002:
---------------------------------------------
We have three different problems here. I fixed the first in the dtests at
https://github.com/riptano/cassandra-dtest/commit/d423d53a26008b73abe6322e99c07e75abcf7f3a
so they use globbing for the directory names, which should fix everything.
And indeed, the test now passes. However, 'nodetool snapshot -t foo' will
create a snapshot of all the system keyspaces, but none of the actual data
keyspaces, so that's the second problem. The third is that this test passes
regardless, because it's a stupid test that just checks for schema agreement,
and not actual data in the snapshot.
