jay vyas updated BIGTOP-1453:
-----------------------------
Description:
Hi folks.
Looks like rc08 is using the old mahout, not the new one. I.e. its build for
*hadoop 0-1x*.. not for *hadoop 2x* .Poking aroudn on RC testing today, I
found this.
1) yum list output shows:
{noformat}
mahout.noarch 0.9.6-1.el6
@Bigtop
{noformat}
The 0.9.6-*-1* seems suspicious.
2) And I ran the mahout tests on a clean RC08 repo, and I got some errors
indicating that it was built for hadoop 1 {{class found but interface
expected}}... indicating that it is an older mahout api which is running the
job.
(a side note : i also saw that pom.xml has references to hadoop 0.23, but
looking at other mahout packages from vendors, its clear that some how that
remains in the mahout pom for some reason or another , so thats not an issue.
the main evidence pointing to bad mahout version is that #2 error i sited above
)

3) Finally, in the pom.xml that is in mahout-core.jar, the hadoop version built
against
is hadoop 0.23
