What changes were proposed in this pull request?
(In the PR, I propose to use Alluxio to help store shuffle data in order to improve the stability of complicated OLAP task.
Motivation
In original ways, when there is a shuffle fetch failure (NodeManager(shuffle service) crashed), spark will rerun previous stage to reproduce shuffle data. This way works well, but in some cases we cannot accept the recalculation price.
In this PR, when there is a shuffle fetch failure , reduce will retry fetch shuffle data from Alluxio to avoid recalculation
Usage
spark.alluxio.shuffle.enabled tureHow was this patch tested?
