-------------------------------------

Hi [~tgraves], would you mind me taking a crack at this if you're not working 
on it.

> YarnShuffleService should use YARN getRecoveryPath() for leveldb location

>                 Key: SPARK-14963
>                 URL: https://issues.apache.org/jira/browse/SPARK-14963
>             Project: Spark
>          Issue Type: Improvement
>          Components: Shuffle, YARN
>    Affects Versions: 1.6.1
>            Reporter: Thomas Graves
>
> The YarnShuffleService, currently just picks a directly in the yarn local 
> dirs to store the leveldb file.  YARN added an interface in hadoop 2.5 
> getRecoverPath() to get the location where it should be storing this.
> We should change to use getRecoveryPath(). This does mean we will have to use 
> reflection or similar to check for its existence though since it doesn't 
> exist before hadoop 2.5
