--------------------------------
Summary: Use flink shaded jacson to parse flink-conf.yaml
Key: FLINK-29366
URL: https://issues.apache.org/jira/browse/FLINK-29366
Project: Flink
Issue Type: Improvement
Components: API / Core
Affects Versions: 1.13.3
Reporter: Yuan Kui
Now we use a simple
implementation(org.apache.flink.configuration.GlobalConfiguration#loadYAMLResource)
to parse flink-conf.yaml, which can only parse key-value pairs.
Although there have been discussions on this issue
historically(see:https://github.com/stratosphere/stratosphere/issues/113)
but I think that in the actual production environment, we often need to config
complex structure into flink-conf.yaml. At this time, the yaml libary is
required for parsing, so I suggest to use the yaml library to parse
flink-conf.yaml instead of our own implementation.
In fact, the flink-core module already has a dependency on flink-shaded-jackson
which could parse yaml format, we can use this jar without more dependencies.
