Subject [jira] [Commented] (HBASE-7226) HRegion.checkAndMutate uses incorrect comparison result for <, <=, > and >=
Date Wed, 25 Dec 2013 18:32:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13856637#comment-13856637

Lars Hofhansl commented on HBASE-7226:
--------------------------------------

Let's also use some common sense :)

I certainly do not have to "approve" every bug fix for 0.94; nor do I want to.
Can't speak for them, but [~stack] and [~apurtell] will probably not want to do that for each
bug fix either.

For 0.94 I have been building the release directly from the svn tag (so there is also no need
to do a freeze for release purposes - of course there might be other reasons, though).

> in HRegion.checkAndMutate, incorrect comparison results are used for <, <=, >
and >=, as below:
>           switch (compareOp) {
>           case LESS:
>             matches = compareResult <= 0;  // should be '<' here
>             break;

>             matches = compareResult < 0;  // should be '<=' here
>             break;
>           case EQUAL:
>             matches = compareResult == 0;
>             break;
>           case NOT_EQUAL:
>             matches = compareResult != 0;
>             break;
