[jira] [Created] (IMPALA-7652) Fix BytesRead for Kudu scans

Thomas Tauber-Marshall created IMPALA-7652:

             Summary: Fix BytesRead for Kudu scans
                 Key: IMPALA-7652
                 URL: https://issues.apache.org/jira/browse/IMPALA-7652
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 3.1.0
            Reporter: Thomas Tauber-Marshall


In the runtime profile, all scan nodes have a BytesRead counter. Kudu scan nodes do not actually set this counter, which creates confusion when Kudu scans report 0 bytes read even though they did in fact read data.

We should either fill in this counter for Kudu scans, or if its difficult to get the count of bytes read from Kudu then we should eliminate the counter for Kudu scan node profiles.
