Danny Chen updated HUDI-2321:
-----------------------------
Description:
Based on the discussion on stackoverflow:
https://stackoverflow.com/questions/1771679/difference-between-threads-context-class-loader-and-normal-classloader
The {{Thread.currentThread().getContextClassLoader()}} should never be used
because the context classloader is not immutable, user can overwrite it when
thread switches, it is also nullable.
The objection here: https://stackoverflow.com/a/36228195 says the the
{Thread.currentThread().getContextClassLoader()}} is a JDK design error and the
context classloader is never suggested to be used. The API that needs
classloader should ask the user to set up the right classloader.
was:Fix ClassLoader error due to HoodieConfig$setDefaults() method call
reflection.
> Use the caller classloader for ReflectionUtils
