[jira] [Created] (HDFS-5451) add more debugging for cache rescan

Colin Patrick McCabe created HDFS-5451:
------------------------------------------

             Summary: add more debugging for cache rescan
                 Key: HDFS-5451
                 URL: https://issues.apache.org/jira/browse/HDFS-5451
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: 3.0.0
            Reporter: Colin Patrick McCabe
            Assignee: Andrew Wang


It would be nice to have message at DEBUG level that described all the decisions we made for cache entries.  That way we could turn on this debugging to get more information.  We should also store the number of bytes each PBCE wanted, and the number of bytes it got, plus the number of inodes it got, and output those in {{listDirectives}}.
