Description

IMPALA-12544 uses  "progress.total_fragment_instances > 0:", but total_fragment_instances is None if the server is older and does not know this Thrift member yet (added in IMPALA-12048). https://github.com/apache/impala/blob/fb3c379f395635f9f6927b40694bc3dd95a2866f/shell/impala_shell.py#L1320

 

This leads to error messages in interactive shell sessions when progress reporting is enabled.
