From the post:
Apache Hama is one of the under-hyped projects in the Hadoop ecosystem but gaining a lot of traction steadily with the efforts of its committers. “Apache Hama is a pure BSP (Bulk Synchronous Parallel) computing framework on top of HDFS (Hadoop Distributed File System) for massive scientific computations such as matrix, graph and network algorithms.”

You won’t learn Hama over the weekend but you can get a start towards a new skill to list at LinkedIn.
