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.
