Well until now this integration test failed only on MacOs. On Ubuntu it went through and as well on Travis (our CI infrastructure in the cloud) - as you can see from the CI platform. Since most of the clusters run on Linux, we did not deeper investigate. I think it is just an issue in the Hadoop Cluster libraries for unit testing (MiniyarnCluster). You can deactivate this integrationTest for now and I will check if I find the root cause. Deactivate it by puttting @Disable in front of the method mapReduceGenesisBlockTest (https://github.com/ZuInnoTe/hadoopcryptoledger/blob/master/examples/mapreduce-bitcoinblock/src/integration-test/java/org/zuinnote/hadoop/bitcoin/example/MapReduceBitcoinBlockIntegrationTest.java). It will build fine and run fine (we tested it on HDP) and you find the jar in build/libs. All non-Mapreduce applications do not show this issue from our experience.
