> "hdfs://namenodehost/parent/child" and "/parent/child" seems to be the correct filename formats for HDFS based on [1] but we currently support format "hdfs://parent/child".
> To not break existing users, we have to either (1) somehow support both versions by default (based on [2] seems like HDFS does not allow colons in file path so this might be possible) (2) make  "hdfs://namenodehost/parent/child" optional for now and change it to default after few versions.
> We should also make sure that Beam Java and Python HDFS file-system implementations are consistent in this regard.
