    Thanks for the review @uce. I addressed your comments.
    
    I fixed the problem with Hadoop 2.6.0 by relocating Flink's curator dependency to `org.apache.flink.shaded.org.apache.curator`.
Furthermore, I bumped `flink-shaded-curator's` Guava version to Flink's Guava version so that
we don't include too many different Guava versions in the resulting `flink-dist.jar`.

> Add master high availability support for Yarn. The idea is to let Yarn restart a failed
application master in a new container. For that, we set the number of application retries
to something greater than 1. 
> From version 2.4.0 onwards, it is possible to reuse already started containers for the
TaskManagers, thus, avoiding unnecessary restart delays.
> From version 2.6.0 onwards, it is possible to specify an interval in which the number
of application attempts have to be exceeded in order to fail the job. This will prevent long
running jobs from eventually depleting all available application attempts.
