Details

    • Migration from Log4j1.x to Log4j2

    Description

      Log4J2 has some great benefits and can benefit hive significantly. Some notable features include
      1) Performance (parametrized logging, performance when logging is disabled etc.) More details can be found here https://logging.apache.org/log4j/2.x/performance.html
      2) RoutingAppender - Route logs to different log files based on MDC context (useful for HS2, LLAP etc.)
      3) Asynchronous logging

      This is an umbrella jira to track changes related to Log4j2 migration.
