Edward Capriolo commented on HIVE-1626: --------------------------------------- IT is not as easy as it seems. Many usages for example are in antlr generated classes and such. > 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: Edward Capriolo > > 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)
