Change subject: IMPALA-6997: Avoid redundant dumping in SetMemLimitExceeded() ...................................................................... IMPALA-6997: Avoid redundant dumping in SetMemLimitExceeded() When a UDF hits a MemLimitExceeded, the query does not immediately abort. Instead, UDFs rely on the caller checking the query_status_ periodically. This means that on some codepaths, UDFs can call SetMemLimitExceeded() many times (e.g. once per row) before the query fragment exits. RuntimeState::SetMemLimitExceeded() currently constructs a MemLimitExceeded Status and dumps it for each call, even if the query has already hit an error. This is expensive and can delay an fragment from exiting when UDFs are repeatedly hitting MemLimitExceeded. This changes SetMemLimitExceeded() to avoid dumping if the query_status_ is already not ok.
