> Key: BOOKKEEPER-1045
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1045
> Project: Bookkeeper
> Issue Type: Test
> Reporter: Matteo Merli
> Assignee: Matteo Merli
> Priority: Minor
> Fix For: 4.5.0
>
>
> The current Maven Surefire configuration is using:
> {code:xml}
> <forkMode>always</forkMode>
> {code}
> This is a deprecated config and apparently it's not creating new processes
> for each test as intended.
> Currently the tests are leaking a big number of files and threads due to
> several reasons:
> * Tests that instantiate bookies and call shutdown() without calling start()
> before are creating and initializing the ledger storage but not closing it,
> leaking threads and several fds
> * ZooKeeperClient sometimes doesn't shutdown the zk handle if the test
> completes too quickly, leaking sockets.
> * Several tests are passing bad config, so the bookie/client start gets
> exception (on purpose) and then doesn't clean up some partial objects.
> * ...
> That make running the test suite to be dependent on ulimit of the machine.
> Until we can fix (almost) all the test to do proper cleanup, we should make
> maven to run tests in separated processes.
