compatible with 1.x
## What changes were proposed in this pull request?
SPARK-12130 make 2.0 shuffle service incompatible with 1.x. So in
[http://apache-spark-developers-list.1001551.n3.nabble.com/YARN-Shuffle-service-and-its-compatibility-td17222.html](url)
we should maintain compatibility between Spark 1.x and Spark 2.x's shuffle
service.
I put string comparison into executor's register at first avoid string
comparison in getBlockData every time.
