ASF GitHub Bot commented on FLINK-2380: --------------------------------------- Github user rmetzger commented on the pull request: https://github.com/apache/flink/pull/1524#issuecomment-182065768 I identified the following issues: - Setting the configuration using the yarn session "dynamic properties": `./bin/yarn-session.sh -n 2 -Dfs.default-scheme=hdfs:///` does not really work (the configuration parameter shows up in the web interface, but the job fails) - Setting a false schema leads to a null pointer exception on job submission. In the flink-conf.yaml, I have `fs.default-scheme: thisIsWrong`. Look at this: ``` org.apache.flink.client.program.ProgramInvocationException: The program execution failed: Cannot initialize task 'DataSink (CsvOutputFormat (path: /user/robert/elasdoijwef,

Versions: 0.9, 0.10.0 > Reporter: Ufuk Celebi > Assignee: Klou > Priority: Minor > Labels: starter > Fix For: 1.0.0 > > > File inputs use "file://" as default prefix. A user asked to make this > configurable, e.g. "hdfs://" as default. > (I'm not sure whether this is already possible or not.
