Subject [jira] [Commented] (HBASE-10548) PerfEval work around wrong runtime dependency version
Date Mon, 17 Feb 2014 13:44:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13903239#comment-13903239
] 

Nicolas Liochon commented on HBASE-10548:
-----------------------------------------

We can commit the change, but there is something I don't get, at least for trunk (I haven't
checked 0.98 & 0.96): hbase pom seems clean, and does require common:math:2.2, whatever
the hadoop version. How comes we're finally installed with the 2.1 version?

I mean, we don't care for this specific case, but if HBase requires the 2.2 version, it should
not be deployed with an older one. Here the error message is clear and it's in the test code,
but it could be less clear and in the production code...
