Change subject: IMPALA-7163: Implement a state machine for the QueryState class ...................................................................... Patch Set 7: (1 comment) http://gerrit.cloudera.org:8080/#/c/10813/7/be/src/runtime/query-state.cc File be/src/runtime/query-state.cc: http://gerrit.cloudera.org:8080/#/c/10813/7/be/src/runtime/query-state.cc@479 PS7, Line 479: { : unique_lock<SpinLock> l(status_lock_); : query_status_ = Status::CANCELLED; : } > No, it makes sense to preemptively set this since a Cancel() is a query wid As discussed in person, we this may overwrite earlier error status during prepare / execution. Also, if we don't have these statements here, the first fragment to cancel will set query_status_ to Status::CANCELLED anyway. -- To view, visit http://gerrit.cloudera.org:8080/10813 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iec5670a7db83ecae4656d7bb2ea372d3767ba7fe Gerrit-Change-Number: 10813 Gerrit-PatchSet: 7 Gerrit-Owner: Sailesh Mukil <[email protected]> Gerrit-Reviewer: Bikramjeet Vig <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Joe McDonnell <[email protected]> Gerrit-Reviewer: Michael Ho <[email protected]> Gerrit-Reviewer: Sailesh Mukil <[email protected]> Gerrit-Comment-Date: Mon, 30 Jul 2018 18:08:13 +0000 Gerrit-HasComments: Yes
