Hadoop Client in WildFly – A Difficult Marriage (Part 2)

After writing about the first impressions about Hadoop and its WildFly integration, I did some more research and work to bring Hadoop into JavaEE on WildFly in a more elegant way.

The follow-up idea after putting Hadoop into an EAR for isolation was to isolate Hadoop and HBase clients into a WildFly module. Both clients work very well in a Java SE environment, so the idea was to use these modules which are not container managed (like Java SE) to provide the functionality to be used in a container.

The resulting (so far) module.xml is:

For HBase client, the module.xml looks like this:

For the modules above, I cannot garantee the completeness of all dependencies, but for the use cases I have at hand, these modules work.
