Problem Description

The current streaming Flink job does not record GC logs, making it impossible to view GC related information. In order to solve this problem, the flink engine loads the env.java.opts configuration in flink-config.yaml. The parameter with the same name submitted by the streamis job has a higher priority than the env.java.opts value of the default configuration file, and must be deduplicated.

flink loads env.java.opts configuration

Use case

Solutions

In FlinkisEngineConnFactory, first read the default flink-config.yaml file in the service and obtain the value of the env.java.opts parameter.
Get the user's env.java.opts, split it first by spaces, and then by equal signs. If there are duplicates, replace them with the user's values. If there are no duplicates, add them after the parameters.
