------------------------------------
Summary: log4j race condition during shutdown
Key: SPARK-47220
URL: https://issues.apache.org/jira/browse/SPARK-47220
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.3.0
Reporter: Holden Karau
Assignee: Holden Karau
There is a race condition during shutdown which can result in a few different
errors:
* ERROR Attempted to append to non-started appender
* ERROR Unable to write to stream
Since I've only seen it during stop() triggered within a shutdown hook I
believe this is caused by the parallel execution of shutdown hooks (see
[https://stackoverflow.com/questions/17400136/how-to-log-within-shutdown-hooks-with-log4j2]
)
