Re: Getting below exception while submitting Jar in task manager


Based on a quick search I think it has to do with the way how you use Spring to package your "HikariDataSource".

Does this SO link help:

Hi,

I am building data consumer using Flink + Spring boot + Mysql + Kafka + Elasticsearch. I am using mvn clean package command to create a jar and submitting it to task manager on Kubernetes.
The same jar works perfectly in local.

I am adding the exception shown in task manager logs. 

Please help me out. I tried everything :( :(
