Subject [jira] [Commented] (GIRAPH-798) Upgrade Giraph to Java7 and fix all dependencies
Date Wed, 11 Dec 2013 05:26:25 GMT


Avery Ching commented on GIRAPH-798:

I've been a bit busy, but understand the frustration here.  Let me see if I can find a fix
for the other Hadoop versions.  Part of the problem is that we have so many versions.  I did
test more than just the Facebook version.  I don't understand how Java 7 causes any breakage.
 Please understand that in the old way, we have a lot of issues due to different versions
of the same library being included in a single jar.  I'll try to spend the next day or two
trying to find a workaround.

> We need to upgrade to Java 7, Java 6 is no longer supported and Java 7 provides a lot
of great new features.
> Additionally, we have a mess of dependencies.
> Incompatible versions, unspecified dependencies, and duplicate classes.  We will add
checks for all of them.
> For now, full checks are provided for the profiles
> hadoop_0.20.203
> hadoop_1.0
> hadoop_facebook
> Also, the hcatalog module is not fully fixed and excluded from the checking.  We can
fix this in the future.
