- Method Detail
  - getPartitionPath
```
String getPartitionPath(Tuple tuple)
```
    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 "/"
    
    Parameters:
    
    tuple - The tuple for which the relative path is being calculated.
