Hi all,
when using the web client to upload and run a jar, the optimizer plan for
my program does not appear.
I have checked the "Show optimizer plan" box and provided args in the
Arguments field.
When I continue to submit the job, it runs correctly. There is no problem
when using the plan visualizer tool.
Checking the webclient logs, I see this exception in the .log file:
org.apache.flink.client.program.ProgramInvocationException: The program
plan could not be fetched. The program silently swallowed the control flow
exceptions.

and the usage message in the .out file, as if I did not provide the correct
number of arguments (which I did).
If it helps, here's the program I was trying to visualize:
https://github.com/vasia/incubator-flink/blob/semimetric-preprocessing/flink-examples/flink-java-examples/src/main/java/org/apache/flink/examples/java/preprocessing/Jaccard.java
Anything I'm missing here?
Thanks,
V.
