Github user afs commented on the pull request: https://github.com/apache/jena/pull/87#issuecomment-123349424 Hadoop 2.7.0 was first released in April of this year and marked as not a production release. 2.7.1 was this month (July). AFAICT neither CDH nor HDP are using 2.7.x at all. Hadoop installations don't get upgraded very frequently; it's "non-trivial". IMO it is better to wait for users to ask for an update to get the pacing right.
