-------------------------------
Summary: Avoid Excessive logging from ContextCleaner
Key: SPARK-28676
URL: https://issues.apache.org/jira/browse/SPARK-28676
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.4.3, 2.3.3, 3.0.0
Reporter: Ajith S
In high workload environments, ContextCleaner seems to have excessive logging
at INFO level which do not give much information. In one Particular case we see
that ``INFO ContextCleaner: Cleaned accumulator`` message is 25-30% of the
generated logs. We can log this information for cleanup in DEBUG level instead.
