HBASE-27720 TestClusterRestartFailover is flakey due to metrics assertion #5110

ndimiduk · 2023-03-15T14:53:24Z

This test has been flakey. When it is rerun by surefire, the underlying minicluster isn't completely cleaned. specifically, the metics system isn't reset. The result is an otherwise successful re-run is failed because there's 8 or 12 SCPcounts instead of the 4 that a single run of the test would otherwise produce. Thus, assert of a multiple of 4.

Can not reset the metrics system in the AfterClass method or BeforeClass method?

Posted a new patch that (I think) will reset the master metrics each time the mini cluster is started.
