      Description

      I've seen this a few times by now:

                 - BytesRead: 571.14 MB (598886266)
                 - BytesReadDataNodeCache: 0
                 - BytesReadLocal: 1.12 GB (1197772532)
                 - BytesReadRemoteUnexpected: 0
                 - BytesReadShortCircuit: 1.12 GB (1197772532)
      

      Haven't tried reproducing it on purpose, just keeps popping up. Counters like this will get more important in cloud-backed clusters since we'll have a mismatch between our charts and what the user ends up paying for S3-based reads.
