---------------------------------------

             Summary: FSOutputSummer NPEs in ctor if bytes per checksum  set to 0
                 Key: HADOOP-12831
                 URL: https://issues.apache.org/jira/browse/HADOOP-12831
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


If you set the number of bytes per checksum to zero, 
{code}    conf.setInt(LocalFileSystemConfigKeys.LOCAL_FS_BYTES_PER_CHECKSUM_KEY, 0)
{code}
then create a "file://" instance, you get to see a stack trace
