Andy Seaborne commented on JENA-842:
------------------------------------
I'm fine with just rolling back the {{<dependencyManagement>}} for now and
making restricted use of Guava in jena-tdb (eventually; cache not done there
yet anyway) and jena-csv.
jena-csv usage is only in {{PropertyTableHashMapImpl}}. It looks like it can be
replaced with the less good but adequate for the task oaj.atlas.lib.MultiMap.
> Elephas IO library does not build
> ---------------------------------
>
> Key: JENA-842
> URL: https://issues.apache.org/jira/browse/JENA-842
> Project: Apache Jena
> Issue Type: Bug
> Components: RDF Tools for Hadoop
> Reporter: Rob Vesse
> Assignee: Rob Vesse
> Fix For: Jena 2.12.2
>
>
> Currently the Elephas modules no longer build due to a bug in the upstream
> Hadoop libraries related to Guava - HADOOP-11032
> Rolling back to 752646c i.e. prior to my merging of the latest Jena master
> changes the issue does not manifest which means this likely relates to the
> introduction of Guava as a dependency into Jena since the Hadoop libraries
> were relying on a really old version of Guava. Looking at {{mvn
> dependency:tree}} this indeed appears to be the case since the managed
> dependency of Guava in the Jena parent POM overrides the transitive
> dependency from Hadoop
> A temporary workaround may be to override back to the outdated Guava in the
> elephas POM while awaiting a fix for the Hadoop issue
