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

             Summary: Add metrics for reading from remote scratch paths
                 Key: IMPALA-10508
                 URL: https://issues.apache.org/jira/browse/IMPALA-10508
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Yida Wu


For reading data from a remote scratch path, the data can be fetched from the local buffer if the file hasn't been uploaded yet, or fetched from remote filesystem.

The metrics can help to identify how much data is read from the local buffer, how much is from the remote filesystem.
