Quickstart Issue

[Will Walters]

Hello,
I am attempting to run the Beam quickstart with Flink on a Yarn cluster. 
However, I cannot find a file path which gets Flink to recognize the input 
file. I have tried local, absolute, and hdfs filepaths, and none of them have 
seemed to work. Does anyone have advice about what form the filepaths should be 
in?
Thank you,Will Walters.
