Sean Busbey commented on ACCUMULO-2781:
---------------------------------------
Just a note of clarification on keeping ITs independent: the static handling of
zookeeper caching (i.e. in fate.ZooSession) requires us to have the ITs in
different JVMs. Once anyone calls ZooSession.shutdown(), all future attempts to
use that JVM will fail.
I *think* all of our unit tests don't make use of the ZooSession facilities,
but it's worth a quick check by whomever handles implementing this change.
> Unit tests should reuse forks by default

> Key: ACCUMULO-2781
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2781
> Project: Accumulo
> Issue Type: Bug
> Components: build
> Affects Versions: 1.6.0
> Reporter: Christopher Tubbs
> Fix For: 1.6.1, 1.7.0
>
>
> The default value for maven-surefire-plugin's reuseForks is true. This is set
> to false in our pom.xml in order to keep ITs independent. This inadvertently
> affects unit tests also, and causes unit tests to create a new JVM for each
> test class.
> These should be separated, and the default for unit tests
> (maven-surefire-plugin's execution) should be {{reuseForks=true}}, and the
> default for ITs (maven-failsafe-plugin's execution) should be
> {{reuseForks=false}} (as it is now).
