Subject [jira] [Created] (HDFS-3505) DirectoryScanner does not join all threads in shutdown
Date Tue, 05 Jun 2012 00:19:23 GMT
Colin Patrick McCabe created HDFS-3505:

             Summary: DirectoryScanner does not join all threads in shutdown
                 Key: HDFS-3505
                 URL: https://issues.apache.org/jira/browse/HDFS-3505
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor

DirectoryScanner does not join all the threads it spawned during DirectoryScanner#shutdown.

This can lead to rare failures in TestDirectoryScanner when some threads linger past their
designated expiration date and cause interference between different test runs.

The fix is to call ExecutorService#awaitTermination.
