I'm trying to use the wordcount example with the local file system, but it's
giving me permissions error or it's not finding it. It works just fine for
input and output on S3. What is the correct URI usage for the local file system
and HDFS?
I have installed Flink on EMR and am just using the flink run script to start
the job:
% flink run -m yarn-cluster -yn 2
/usr/lib/flink/examples/streaming/WordCount.jar --input
file:///home/hadoop/LICENSE.txt

Are there really permissions issues and if so how would I correct that (since
permissions are ostensibly correct for any other application)?
For HDFS, I tried this but got a protobuf exception:
% flink run -m yarn-cluster -yn 2
/usr/lib/flink/examples/streaming/WordCount.jar --input
hdfs://ec2-54-208-188-194.compute-1.amazonaws.com:50070/user/hadoop/LICENSE.txt
