Hi folks, We're planning on releasing 3.0.0-alpha3 next month (May 15th). The biggest piece of work targeted for this release is completing user-facing erasure coding changes. This is on track, but there are some other blockers that we also need to push on.
I've also written a new status update on the wiki, also reproduced below. https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+3+release+status+updates Thanks everyone for their hard work thus far!
