Sounds good. I was thinking we could put a note in the Reference Guide for this problem. There are sections on JDK support metrics and Hadoop support metrics ( https://hbase.apache.org/book.html#basic.prerequisites). They are good places to document this and suggest to use a later version of Hadoop if needed. I can open a JIRA to do it.
