[jira] [Created] (CASSANDRA-7442) Parallelize unit test runner

T Jake Luciani created CASSANDRA-7442:
-----------------------------------------

             Summary: Parallelize unit test runner
                 Key: CASSANDRA-7442
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7442
             Project: Cassandra
          Issue Type: Bug
            Reporter: T Jake Luciani
            Assignee: T Jake Luciani
            Priority: Minor
             Fix For: 2.1.0


Currently we spend ~15 minutes running unit tests.

We can parallelize the unit tests by splitting the classes up across processes and using more cores.

This patch adds a new variable -Dtest.runners=X (default is 1)

Running with 4 runtime goes from 15min to 6min. 
Beyond 1 runner per core I don't see much of a difference
