Roman Shaposhnik commented on MAHOUT-822:
-----------------------------------------
The good news is that the delta between 0.22 and 0.23 is pretty much 0 as far
as Mahout is concerned. I see the very same compilation issues on the
0.23-SNAPSHOT:
http://bigtop01.cloudera.org:8080/job/Bigtop-hadoop23/COMPONENT=mahout,label=centos5/3/console
In general it is a known fact that 0.23 will NOT be API compatible with 0.20 in
certain areas. Changes in the downstream components are needed to accommodate
that. Hence this JIRA.
Finally, are you comfortable with the attach patch to Maven part of Mahout?
