A common interview question for a Hadoop developer position is whether we can control the number of 
mappers for a job.  We can - there are a few ways of controlling the number of mappers, as needed. 
Using NLineInputFormat is one way.

JDK 8 Released

Most of us won’t be able to use/deploy JDK 8 in production for a looong time. But that shouldn’t stop us from using it, right?

It should be possible to sneak in JDK 8 in the back way, the same way we snuck in Groovy and other libraries we wanted to use.

The Test Suite to the rescue

The Maven compiler plugin run in two separate lifecycles, compile and testCompile. Those can be configured separately.
