      Description

      When using DistCP over HTTPFS with data that contains Spark partitions, DistCP fails to access the partitioned parquet files since the "=" characters in file path gets double encoded:
      "/test/spark/partition/year=2019/month=1/day=1"
      to
      "/test/spark/partition/year%253D2019/month%253D1/day%253D1"

      This happens since fsPathItem containing the character '=' is encoded by URLEncoder.encode(fsPathItem, "UTF-8") to '%3D' and then encoded again by new Path(....) to '%253D'.
