Akira Ajisaka commented on YARN-6288:
-------------------------------------
If an exception occurs when the writer is not ready or closed,
{{writer.close()}} is called in the finally clause and throws
IllegalStateException instead of the original exception. That way we cannot
detect what is the original exception. I'd like to catch the original exception
and log it.
