Ismael Juma commented on KAFKA-2688:
------------------------------------
Flavio, assigning this to you as I have removed the SASL code and we now only
need to remove it from `isZkSecurityEnabled`. I hope that's OK.
> Avoid forcing reload of `Configuration`

> Project: Kafka
> Issue Type: Bug
> Components: security
> Reporter: Ismael Juma

> Priority: Critical
> Fix For: 0.9.0.0

>
> We currently call `Configuration.setConfiguration(null)` from a couple of
> places in our codebase (`Login` and `JaasUtils`) to force `Configuration` to
> be reloaded. If this code is removed, some tests can fail depending on the
> test execution order.
> Ideally we would not need to call `setConfiguration(null)` outside of tests.
> Investigate if this is possible. If not, we should at least ensure that
> reloads are done in a safe way within our codebase (perhaps using a lock).
