@zjffdu Nice!
In the past `Spark Tutorial` is the only tutorial note in Zeppelin included
by default. But after this PR, 5 tutorial notes will be shown to Zeppelin new
commers. Since some ppl can try this Pig tutorial before Spark one, more
detailed description will be helpful to users than just saying like below

e.g. short description about Pig / you need to install `hadoop` before
trying to run this tutorial note, and etc etc..
There is good example ([Mahout tutorial
note](https://github.com/apache/zeppelin/blob/master/notebook/2BYEZ5EVK/note.json#L4))
you can refer to.
