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...
