Subject [jira] Commented: (HIVE-545) Use ArrayList instead of Vector in single-threaded Hive code
Date Tue, 25 Aug 2009 19:29:59 GMT

    [ https://issues.apache.org/jira/browse/HIVE-545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747592#action_12747592
] 

Edward Capriolo commented on HIVE-545:
--------------------------------------

Once upon a time, a major factor in changing jobs was over an argument over Vector vs ArrayList
:)  Should the declaration be of type List while instances be ArrayList? 

Do you want help ? I think I can tackle this one with search/replace? then re-run tests?

> Most of the Hive code is single-threaded, but sometimes we are using Vector instead of
the more efficient ArrayList.
> See http://java.sun.com/j2se/1.5.0/docs/api/java/util/ArrayList.html
> "This class (ArrayList) is roughly equivalent to Vector, except that it is unsynchronized."
