We have to be careful with this as modifying the result of keySet() would also modify the original HashSet. I checked all the callsites of getPartitionIds() and apparently everywhere the first step after getting the result is to copy it's items to a separate HashSet so this should be fine. I'll move this cleanup to a separate patch. https://issues.apache.org/jira/browse/IMPALA-7121 -- To view, visit http://gerrit.cloudera.org:8080/10543 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I2a54bc8224bcefe65b83de2df58bb84629f2aa4a Gerrit-Change-Number: 10543 Gerrit-PatchSet: 6 Gerrit-Owner: Gabor Kaszab <gaborkas...@cloudera.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Gabor Kaszab <gaborkas...@cloudera.com> Gerrit-Reviewer: Sailesh Mukil <sail...@cloudera.com> Gerrit-Reviewer: Zoltan Borok-Nagy <borokna...@cloudera.com> Gerrit-Comment-Date: Tue, 05 Jun 2018 08:32:10 +0000 Gerrit-HasComments: Yes
