Paul, Running haveged helped me finish the build and prevent the unit test org.apache.nifi.processors.elasticsearch.PutElasticsearchJsonTest.testLargeInputStringHandling from hanging. I did not realize though initially that I had to actually manually start haveged. I found out that from a user's comment on the article How to Setup Additional Entropy for Cloud Servers Using Haveged <https://www.digitalocean.com/community/tutorials/how-to-setup-additional-entropy-for-cloud-servers-using-haveged>. After starting manually with: sudo service haveged start
I was able to complete the build. Thank you so much for this suggestion and help me getting over this hump. I personally think this test belongs in an integration test so users wouldn't have to install haveged. It is interesting to note in the setup method of org.apache.nifi.minifi.commons.service.StandardFlowPropertyEncryptorTest, the method org.apache.commons.lang3.RandomStringUtils.randomAlphabetic is used and that does not seem to cause an issue.
