Summary: Use Log4j2 instead of unsupported Log4j (1.x) in tests Key: CALCITE-4858 URL: https://issues.apache.org/jira/browse/CALCITE-4858 Project: Calcite Issue Type: Improvement Affects Versions: 1.28.0 Reporter: Stamatis Zampetakis Assignee: Stamatis Zampetakis Fix For: 1.29.0 Currently the logger implementation (for SL4J APIs) that is used in tests is Log4j (1.x) via slf4j-log4j12 dependency. Log4j (1.x) has reached [end of life in 2015|https://blogs.apache.org/foundation/entry/apache_logging_services_project_announces] and using it is highly discouraged for multiple reasons (security, performance, features, etc.) {noformat} 5 August 2015 --The Apache Logging Services™ Project Management Committee (PMC) has announced that the Log4j™ 1.x logging framework has reached its end of life (EOL) and is no longer officially supported. {noformat} The goal of this JIRA is to use the more modern Log4j2 as the chosen implementation for the SLF4J APIs (via log4j-slf4j-impl) in tests. The only modules that cannot benefit from this upgrade are Pig/Piglet due to tight dependencies to log4j API. -- This message was sent by Atlassian Jira (v8.3.4#803005)
