--------------------------------
Summary: Upgrade log4j2 to 2.17.2
Key: SPARK-38544
URL: https://issues.apache.org/jira/browse/SPARK-38544
Project: Spark
Issue Type: Improvement
Components: Build
Affects Versions: 3.3.0
Reporter: Yang Jie
Log4j 2.17.2 has been released to:
* Over 50 improvements and fixes to the Log4j 1.x support. Continued testing
has shown it is a suitable replacement for Log4j 1.x in most cases.
* Scripting now requires a system property be specified naming the languages
the user wishes to allow. The scripting engine will not load if the property
isn't set.
* By default, the only remote protocol allowed for loading configuration files
is HTTPS. Users can specify a system property to allow others or prevent remote
loading entirely.
* Variable resolution has been modified so that only properties defined as
properties in the configuration file can be recursive. All other Lookups are
now non-recursive. This addresses issues users were having resolving lookups
specified in property definitions for use in the RoutingAppender and
RollingFileAppender due to restrictions put in place in 2.17.1.
* Many other fixes and improvements.
