Subject [jira] [Created] (HDFS-5274) Add Tracing to HDFS
Date Sat, 28 Sep 2013 00:53:02 GMT
Elliott Clark created HDFS-5274:
-----------------------------------

             Summary: Add Tracing to HDFS
                 Key: HDFS-5274
                 URL: https://issues.apache.org/jira/browse/HDFS-5274
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: datanode, namenode
            Reporter: Elliott Clark
            Assignee: Elliott Clark


Since Google's Dapper paper has shown the benefits of tracing for a large distributed system,
it seems like a good time to add tracing to HDFS.  HBase has added tracing using HTrace. 
I propose that the same can be done within HDFS.
