Subject [jira] [Commented] (HAMA-431) MapReduce NG integration
Date Tue, 11 Oct 2011 14:17:12 GMT


Thomas Jungblut commented on HAMA-431:

Putting Avro into CP worked fine.
But I'm facing relative huge issues with our project now.

In every of our module, we have hadoop-20.2 as dependency.
SERVER module is depending on API and CORE, now hadoop-20.2 ships within every jar export
/ snapshot build. Old classes override the new ones during the build process.

Should I change the hadoop 20.2 dependency to 23.0 in every module to fix this? I see several
compatibility issues in our main packages, especially with Zookeeper. 

I'm still thinking about just making the whole module depending on a Hama-0.4.0 SNAPSHOT and
develop further. The integration totally sucks.
