METRON-597 Sporadic Failures of Profiler Integration Tests ## [METRON-597](https://issues.apache.org/jira/browse/METRON-597) ### Changes #### MockHTable The MockHTable uses an ArrayList to store a log of Puts that have been submitted against the MockHTable. The MockHTable, along with the put log, is accessed from multiple threads during the integration tests, but it is not thread safe. The Put log is used by multiple tests, but more so by the ProfilerIntegrationTest. This tests polls the list to block the thread until the expected number of Puts have been submitted. This is likely why this test is more impacted by this issue than others. #### Test Validation Some of the test validation was very opinionated about the number of times the Profiler itself had flushed. As the integration test is being validated, the Profiler is running in the background and will continue to flush measurements. The validation was changed to not care how many times the Profiler has flushed measurements to HBase. ### Testing Prior to these changes, the Travis CI build was reliably failing. After making these changes, the Travis CI build has passed at least 6 times in a row. I have also run this repeatedly on my local machine and have not experienced any failures.
