Thought I’d play a little with Hadoop 0.23 (a.k.a YARN, MR2, NextGen Hadoop) and dump my notes here.
Gotta keep my skillz sharp y’all so I don’t become irrelephant. (Yes, that just happened.)
Below I just setup a pseudo-distributed mode setup and run some examples on it, nothing crazy.
I’m hoping to test and write more on how 0.23 differs from the main line 0.20.x, 1.0 and CDH3 releases as well as playing with the NameNode federation and using some other paradigms like MPI, Hama and Spark.
