[jira] [Created] (HDFS-13712) BlockReaderRemote.read() logging improvement

Gergo Repas created HDFS-13712:
----------------------------------

             Summary: BlockReaderRemote.read() logging improvement
                 Key: HDFS-13712
                 URL: https://issues.apache.org/jira/browse/HDFS-13712
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs-client
    Affects Versions: 3.1.0
            Reporter: Gergo Repas
            Assignee: Gergo Repas


Logger.isTraceEnabled() shows up as a hot method via calls from BlockReaderRemote.read(). The attached patch reduces the number of such calls when trace-logging is turned off, and is on-par when the trace-logging is turned on.
