Sergey Shelukhin commented on HIVE-1626: ---------------------------------------- Does this need to be resubmitted again? > stop using java.util.Stack > -------------------------- > > Key: HIVE-1626 > URL: https://issues.apache.org/jira/browse/HIVE-1626 > Project: Hive > Issue Type: Improvement > Components: Query Processor > Affects Versions: 0.7.0 > Reporter: John Sichi > Assignee: Teddy Choi > Attachments: HIVE-1626.2.patch, HIVE-1626.2.patch, HIVE-1626.3.patch > > > We currently use Stack as part of the generic node walking library. Stack > should not be used for this since its inheritance from Vector incurs > superfluous synchronization overhead. > Most projects end up adding an ArrayStack implementation and using that > instead. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
