Hi all,
As part of our projects, I experiment with Flink Monitoring REST API
and, especially, its capabilities of uploading and running jar files.
When I am trying to submit one of our jobs by running a jar previously
uploaded via '/jars/upload', I am getting an 500 Internal Server Error
response with the following body:
{ "errors": [
"org.apache.flink.client.program.ProgramInvocationException: The main
method caused an error." ] }
On the other hand, when I am trying the same with the ‘Word Count’
batch example, execution succeeds.
It must be pointed out that I tried to execute the respective POST
request both via ‘curl’ and Postman, but both failed with the same error.
Do anyone have idea why this may happen?
Thanks in advance,
Konstantinos
