> When the transaction-related tests are run in parallel, some of them are flapping. Most of the failures seem related to the transaction visibility filter not doing it's job. The flapping tests have been moved to NotThreadSafeTransactionIT to prevent build failures. We should figure out the root cause to make sure there are no bugs lurking. One recent example test run that failed is here: https://builds.apache.org/job/Phoenix-master/1424
> To reproduce, copy/paste the tests back to TransactionIT and run the test suite through {{mvn verify}}. The only test category that needs to be run is the ParallelStatsEnabledTest category (which takes about 7mins).
