the class FailForUnsupportedHBaseVersionsIT method testDoesNotStartRegionServerForUnsupportedCompressionAndVersion.

/**
     * Test that we correctly abort a RegionServer when we run tests with an unsupported HBase
     * version. The 'completeness' of this test requires that we run the test with both a version of
     * HBase that wouldn't be supported with WAL Compression. Currently, this is the default version
     * (0.94.4) so just running 'mvn test' will run the full test. However, this test will not fail
     * when running against a version of HBase with WALCompression enabled. Therefore, to fully test
     * this functionality, we need to run the test against both a supported and an unsupported version
     * of HBase (as long as we want to support an version of HBase that doesn't support custom WAL
     * Codecs).
     * @throws Exception on failure
