[jira] [Created] (HDFS-16063) Add toString to EditLogFileInputStream

David Mollitor created HDFS-16063:
-------------------------------------

             Summary: Add toString to EditLogFileInputStream
                 Key: HDFS-16063
                 URL: https://issues.apache.org/jira/browse/HDFS-16063
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: David Mollitor


The class {{EditLogFileInputStream}} is logged at DEBUG level, but has no {{toString}} method, so the logging is of limited value.  Also, put the DEBUG statement behind some guards since it's printing an unbounded list of items.
