Submitting job via Flink web interface giving Null pointer exception

[Ritesh Kumar Singh]

Hi,

I'm not sure if anyone has faced a similar issue with Flink_v1.0.0 that it's behaving differently when I submit a job via command line and when I do the same using Flink web interface. 

The web interface is giving me Null pointer exceptions when the same is working via the command line and from an eclipse environment. Is it some sort of bug that is already known or are there some adjustments that need to be done before uploading the jar?

Thanks,

Hi Ritesh,

We are using Flink 1.0.0 and don’t have issues with using the command line or the web interface.

Can you please share some details on the command you are using and probably a screen shot of the web interface with the values used for submission.

You are running Flink standalone or over Yarn ?

Best,

Abhi

on command line I'm executing: $ flink run project.jar

This is on a Flink standalone mode of deployment using the start-local.sh script. The web interface is running into Null pointer exception on an internal codebase. Weird thing is that it does not happen when submitting the job via commandline

Hi Ritesh,

I tried to run a local flink using the same script and submitted a job successfully via Web interface and command line both.

I suggest to try one of the flink examples.

Streaming Job - https://ci.apache.org/projects/flink/flink-docs-release-1.0/quickstart/run_example_quickstart.html

Batch Job - https://ci.apache.org/projects/flink/flink-docs-release-1.0/apis/batch/examples.html

May be this help in identifying where the problem lies, with the flink setup or the job.

Best,

Abhi
