Description

More log messages would help us to debug EARs faster.

1. Add error log when configuration fetch fails.
2. Add debug log when request proxying / redirection succeed
3. Add error log when request proxying / redirection fails

With effect from AMBARI-14084, each view would have separate log file.

• For Tez view that is /var/log/ambari-server/tez-view/tez-view.log.
• Debug log would be logged only when the debug mode is enabled. (Set log4j.logger.org.apache.ambari.view.tez=DEBUG,tezView in view.log4j.properties for the same)
