This test will test the expire handling of a meta-carrying region server. After HBaseMiniCluster is up, we will delete the ephemeral node of the meta-carrying region server, which will trigger the expire of this region server on the master. On the other hand, we will slow down the abort process on the region server so that it is still up during the master SSH. We will check that the master SSH is still successfully done.

Throws:

Exception

testMetaAssignmentFailure

public void testMetaAssignmentFailure()
                               throws Exception

Master should be able to recover from any unexpected state of meta-region-server znode

Throws:
