Subject [jira] [Updated] (HDFS-5199) Add more debug trace for NFS READ and WRITE
Date Fri, 13 Sep 2013 19:21:51 GMT

Brandon Li updated HDFS-5199:

    Attachment: HDFS-5199.2.patch

Thanks, Jing.

I've moved the constants to Nfs3Utils since they are just used for NFS3 hdfs specifically.

I also moved the debug trace close to read() and write() call are invoked. If we move them
into read() or write() method, we have to insert them into multiple places, which is not as
clean as the a couple lines change in handler method.

> Before more sophisticated utility is added, the simple trace indicating start/end serving
request can help debug errors and collect statistic information.
