             Summary: Support to specify a remote path for job jar
                 Key: FLINK-17632
                 URL: https://issues.apache.org/jira/browse/FLINK-17632
             Project: Flink
          Issue Type: Sub-task
          Components: Client / Job Submission, Deployment / YARN
            Reporter: Yang Wang


After FLINK-13938, we could support to register remote shared libs as Yarn 
local resources and prevent unnecessary uploading and downloading for system 
Flink jars.

However, we still need to specify a local user jar to run a Flink job on Yarn. 
This ticket aims to add the remote path support. It have at least two purposes.
 * Accelerate the submission
 * Better integration with application mode. Since the user main code is 
executed in the cluster(jobmanager), we do not need the user jar exists locally.

A very typical use case is like following.
{code:java}
./bin/flink run-application -p 10 -t yarn-application \
-yD yarn.provided.lib.dirs="hdfs://myhdfs/flink/lib" \ 
hdfs://myhdfs/jars/WindowJoin.jar{code}
