Dan Berindei created ISPN-5534: ---------------------------------- Summary: CreateCacheCommand doesn't properly wait for the cache to stabilize Key: ISPN-5534 URL: https://issues.jboss.org/browse/ISPN-5534 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.0.0.Alpha1, 7.2.2.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Blocker Fix For: 8.0.0.Alpha2 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. {code} while (stm.getCacheTopology().getMembers().size() != expectedSize || stm.getCacheTopology().getPendingCH() != null) { {code} Combined with ISPN-5533, this is causing random failures in the M/R tests, e.g. {noformat} 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) {noformat} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
