Xuan Gong says:

bq. In YARN, we have several unit test for RM HA, too. Such as TestRMFailover. We are using MiniYarnCluster. 
Also, There are many HA unit tests which extend ProtocolHATestBase. So, you can take a look at ProtocolHATestBase, too.



Jing Zhao:

bq. In HDFS there are some HA related unit tests in the {{org.apache.hadoop.hdfs.server.namenode.ha}} package. E.g., TestRetryCacheWithHA. Besides MiniQJMHACluster can be used if we also want to enable QJM in the tests.

> HDFS and YARN use miniclusters in HA mode to simulate the HA modes. If we switched some of our tests to HA mode, we can validate HA compatibility and failure handling
