------------------------------------

             Summary: Pass Accumulo trace functionality through the DFSClient
                 Key: ACCUMULO-1197
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1197
             Project: Accumulo
          Issue Type: Improvement
          Components: trace
            Reporter: Josh Elser
            Assignee: Eric Newton


The tracing functionality used by Accumulo provides nested regions of timing information for
regular operations occurring inside of Accumulo, e.g. scans and compactions. There is basic
functionality to view this information through the Accumulo monitor.

Currently, this tracing doesn't fall through into HDFS. It would be awesome to actually introspect
through the DFSClient, all the way down to the datanode writing to local disk.
