Hoya (HBase on YARN) : Application Architecture by Steve Loughran.
From the post:
At Hadoop Summit in June, we introduced a little project we’re working on: Hoya: HBase on YARN. Since then the code has been reworked and is now up on Github. It’s still very raw, and requires some local builds of bits of Hadoop and HBase – but it is there for the interested.
In this article we’re going to look at the architecture, and a bit of the implementation.
We’re not going to look at YARN in this article -for that we have a dedicated section of the Hortonworks site -including sample chapters of Arun Murthy’s forthcoming book. Instead we’re going to cover how Hoya makes use of YARN.
If you are interested in where Hadoop is likely to go beyond MapReduce and don’t mind getting your hands dirty, this is for you.
