             Summary: TimeRoutedAliasUpdateProcessorTest.testDateMathInStart: multi-threaded race condition due to ZK assumptions
                 Key: SOLR-13943
                 URL: https://issues.apache.org/jira/browse/SOLR-13943
             Project: Solr
          Issue Type: Test
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Chris M. Hostetter


TimeRoutedAliasUpdateProcessorTest does not currently run in many jenkins builds due to being marked BadApple(SOLR-13059) -- however when it does run, the method {{testDateMathInStart}} frequently fails due to what appears to be a multi-threaded race condition in the test logic...

I'll attach some logs from recent failures and my own quick analysis of the problems of how the test appears to be asserting ZK updates.
