          public String getPartitionPath​(Tuple tuple)

      Description copied from interface: `Partitioner`
      Return a relative path that the tuple should be written to. For example, if an HdfsBolt were configured to write to /common/output and a partitioner returned "/foo" then the bolt should open a file in "/common/output/foo"

      A best practice is to use Path.SEPARATOR instead of a literal "/"

      Specified by:
        `getPartitionPath` in interface `Partitioner`
      Parameters:
        `tuple` - The tuple for which the relative path is being calculated.
