Github user nielsbasjes commented on the issue: https://github.com/apache/flink/pull/2330 I managed to resolve the problems with running these unit tests. These problems were caused by version conflicts in guava. Now we have a HBaseMiniCluster that is started, a table with multiple regions is created. And the TableInputFormat is used to extract the rows again. By setting the paralellism to 1 the same TableInputFormat instance is used for multiple regions and succeeds (the problem this all started with). Please review.
