    • testAddingServerBeforeOldIsDead2413

      @Disabled @Test public void testAddingServerBeforeOldIsDead2413() throws IOException
      Test adding in a new server before old one on same host+port is dead. Make the test more onerous by having the server under test carry the meta. If confusion between old and new, purportedly meta never comes back. Test that meta gets redeployed.
      Throws:
      IOException

    • testKillRSWithOpeningRegion2482

      @Disabled @Test public void testKillRSWithOpeningRegion2482() throws Exception
      In 2482, a RS with an opening region on it dies. The said region is then stuck in the master's regions-in-transition and never leaves it. This test works by bringing up a new regionserver, waiting for the load balancer to give it some regions. Then, we close all on the new server. After sending all the close messages, we send the new regionserver the special blocking message so it can not process any more messages. Meantime reopening of the just-closed regions is backed up on the new server. Soon as master gets an opening region from the new regionserver, we kill it. We then wait on all regions to come back on line. If bug is fixed, this should happen soon as the processing of the killed server is done.
      Throws:
      Exception
