Hudson commented on ACCUMULO-1382:
----------------------------------
Integrated in Accumulo-Trunk-Hadoop-2.0 #209 (See
[https://builds.apache.org/job/Accumulo-Trunk-Hadoop-2.0/209/])
ACCUMULO-1382 Make PairLexicoder use a ComparablePair, so the
Comparable-ness of its parameters can be enforced. Also fixed javadocs, header
comments, formatting, and warnings introduced by ACCUMULO-1336. (Revision
1479448)
Result = SUCCESS

> Pair incorrectly assumes its components are Comparable
> ------------------------------------------------------
>
> Key: ACCUMULO-1382
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1382
> Project: Accumulo
> Issue Type: Bug
> Reporter: Christopher Tubbs
> Assignee: Christopher Tubbs
> Labels: warning
> Fix For: 1.6.0
>
>
> In trunk (for 1.6.0), Pair<A,B> was made Comparable, but makes assumptions
> that A and B are Comparable. This should either be checked in its compareTo
> method explicitly, or should be enforced in the generic parameters. This
> assumption is a runtime bug-in-waiting.
> It looks like this was added to support some of the new Lexicoders.
> I did a rough check to see the implications of enforcing the parameters to be
> Comparable (changing it from Pair<A,B> to Pair<A extends Comparable<A>,B
> extends Comparable<B>>), and it looks like there's a problem because we use
> this class with generated thrift code, which are not Comparable objects.
> It might be better to make a ComparablePair that extends Pair, for use in the
> Lexicoders, instead of making Pair itself Comparable.
