[SPARK-21138] [YARN] Cannot delete staging dir when the clusters of
"spark.yarn.stagingDir" and "spark.hadoop.fs.defaultFS" are different
## What changes were proposed in this pull request?
When I set different clusters for "spark.hadoop.fs.defaultFS" and
"spark.yarn.stagingDir" as followsï¼
```
spark.hadoop.fs.defaultFS hdfs://tl-nn-tdw.tencent-distribute.com:54310
spark.yarn.stagingDir hdfs://ss-teg-2-v2/tmp/spark
```
The staging dir can not be deleted, it will prompt following message:
```
java.lang.IllegalArgumentException: Wrong FS:
hdfs://ss-teg-2-v2/tmp/spark/.sparkStaging/application_1496819138021_77618,
expected: hdfs://tl-nn-tdw.tencent-distribute.com:54310
