------------------------------------
Summary: Allow passing a ClassLoader to EnvironmentSettings
Key: FLINK-15635
URL: https://issues.apache.org/jira/browse/FLINK-15635
Project: Flink
Issue Type: Improvement
Components: Table SQL / API, Table SQL / Planner
Reporter: Timo Walther
We had a couple of class loading issues in the past because people forgot to
use the right classloader in {{flink-table}}. The SQL Client executor code
hacks a classloader into the planner process by using {{wrapClassLoader}} that
sets the threads context classloader.
Instead we should allow passing a class loader to environment settings. This
class loader can be passed to the planner and can be stored in table
environment, table config, etc. to have a consistent class loading behavior.
