dlg99 opened a new issue #3162:
URL: https://github.com/apache/bookkeeper/issues/3162


   `mvn test -f stream/distributedlog/core/pom.xml` 
   ```
   [ERROR] Tests run: 7, Failures: 0, Errors: 3, Skipped: 0, Time elapsed: 112.456 s <<< FAILURE! - in org.apache.distributedlog.TestTruncate
   [ERROR] org.apache.distributedlog.TestTruncate.testTruncation  Time elapsed: 20.812 s  <<< ERROR!
   org.apache.distributedlog.exceptions.BKTransmitException: Failed to write to bookkeeper; Error is (-6) Not enough non-faulty bookies available : -6
   ```
   
   The tests flake (sometimes fail with error above, sometime VM crashes) on my mac but pass if I run them one by one:
   ```
   mvn test -f stream/distributedlog/core/pom.xml -Dtest=org.apache.distributedlog.TestTruncate#testPurgeLogs
   mvn test -f stream/distributedlog/core/pom.xml -Dtest=org.apache.distributedlog.TestTruncate#testTruncation
   mvn test -f stream/distributedlog/core/pom.xml -Dtest=org.apache.distributedlog.TestTruncate#testExplicitTruncation
   mvn test -f stream/distributedlog/core/pom.xml -Dtest=org.apache.distributedlog.TestTruncate#testOnlyPurgeSegmentsBeforeNoneFullyTruncatedSegment
   mvn test -f stream/distributedlog/core/pom.xml -Dtest=org.apache.distributedlog.TestTruncate#testPartiallyTruncateTruncatedSegments
   ```
   
   probably there is some race in test setup/teardown
