[SPARK-19705][SQL] Preferred location supporting HDFS cache for FileS⦠â¦canRDD Added support of HDFS cache using TaskLocation.inMemoryLocationTag NewHadoopRDD and HadoopRDD both support HDFS cache using TaskLocation.inMemoryLocationTag where "hdfs_cache_" is added to hostname which is then interpretted by scheduler With this enhacement same tag ("hdfs_cache_") will be added to hostname if FilePartition only contains single file and the file is cached on one or more host Current implementation would not cased where FilePartition would have multiple files as preferredLocation calculation is more complex. ## What changes were proposed in this pull request?
