[jira] [Created] (IMPALA-11698) Ozone local reads do not update local-bytes-read metric
Michael Smith created IMPALA-11698:
--------------------------------------
Summary: Ozone local reads do not update local-bytes-read metric
Key: IMPALA-11698
URL: https://issues.apache.org/jira/browse/IMPALA-11698
Project: IMPALA
Issue Type: Bug
Components: Backend
Reporter: Michael Smith
https://github.com/apache/impala/blob/7a28295905e97e41503670bbdd92e64ea47f0078/be/src/runtime/io/hdfs-file-reader.cc#L394-L417 updates several metrics that were previously specific to HDFS. The local-bytes-read metric makes sense for Ozone as Ozone datanodes can be co-located with Impala executors. It's currently not updated for co-located Ozone reads.
