Hi! I still believe it is an issue of the class loader. To test that, can you remove the HBase jar file from the Flink lib directory, and make it part of the job jar? (Either as a fat jar, or by creating a "lib" folder inside your job jar file and putting the hbase.jar into that folder)
That way Hbase would be loaded through the user code class loader and hopefully use that class loader to search for the XML files. Please let us know if that solves it. Stephan
