-----------------------------------

             Summary: Isolate and rerun unit tests that fail following a code commit
                 Key: HBASE-11381
                 URL: https://issues.apache.org/jira/browse/HBASE-11381
             Project: HBase
          Issue Type: Task
            Reporter: Dima Spivak


It's not uncommon to see that, after changes are committed to a branch, a set of unit tests will begin to fail and Hudson will add a comment to the relevant JIRAs reporting on the unsuccessful build. Unfortunately, these test failures are not always indicative of regressions; sometimes, the problem is with infrastructure and simply rerunning the tests can make them go green again.

I propose modifying the Jenkins job that is triggered by a code commit to address this problem. In particular, the job could use the reports generated by the Maven Surefire plugin to generate a list of tests to rerun. These tests can be set to rerun any number of times and a threshold ratio of passes-to-fails can be the deciding factor in whether a real bug has been introduced following a change in HBase.
