   > It seems to me that functions under `python/pyspark/sql/pandas/utils.py` are used internally - in the existing Spark source code only.
   > 
   > A developer API "should" still be called externally, by developers though, e.g. `semanticHash`.

   > So defining a developer API in `utils.py` seems a little unclear to me.
   
   Can we move the `barrier` API definition to proper place ?
