Because of ISPN-5533, CreateCacheCommand.perform() waits for the cache to stabilize with a certain number of members. However, the wait condition is wrong: it will exit the loop when either the number of members is correct or there is no rebalance in progress.
while (stm.getCacheTopology().getMembers().size() != expectedSize && stm.getCacheTopology().getPendingCH() != null) {
should be
while (stm.getCacheTopology().getMembers().size() != expectedSize || stm.getCacheTopology().getPendingCH() != null) {
Combined with ISPN-5533, this is causing random failures in the M/R tests, e.g.
23:17:45,353 ERROR (testng-DistributedFourNodesMapReduceTest:) [UnitTestTestNGListener] Test testInvokeMapReduceOnAllKeysWithResultCache(org.infinispan.distexec.mapreduce.DistributedFourNodesMapReduceTest) failed. java.lang.AssertionError: key 'community' does not have count 2 but 4 at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.assertTrue(Assert.java:41) at org.infinispan.distexec.mapreduce.BaseWordCountMapReduceTest.verifyResults(BaseWordCountMapReduceTest.java:256) at org.infinispan.distexec.mapreduce.BaseWordCountMapReduceTest.verifyResults(BaseWordCountMapReduceTest.java:380) at org.infinispan.distexec.mapreduce.BaseWordCountMapReduceTest.testInvokeMapReduceOnAllKeysWithResultCache(BaseWordCountMapReduceTest.java:175)
