Given the scope of a new major release, the Apache Hadoop community decided to release a series of alpha and beta releases leading up to 3.0.0 GA. This gives downstream applications and end users an opportunity to test and provide feedback on the changes, which can be incorporated during the alpha and beta process. The 3.0.0-alpha1 release incorporates thousands of new fixes, improvements, and features since the previous minor release, 2.7.0, which was released over a year ago. The full  changelog  and  release notes  are available on the Hadoop website, but we’d like to drill into the major new changes that landed in 3.0.0-alpha1.

I am big fan of automation and recently was looking for a way to automatically tweet when I publish a new blog. Found  ifttt.com  which allows to create recipes like these and share with others. The recipes run every 15 minutes, so there is a delay of maximum 15 minutes between publishing a new blog and getting it posted into Twitter.
