Summary: Add EWMA to yarn log4j appenders in Dal
Key: AMBARI-11128
URL: https://issues.apache.org/jira/browse/AMBARI-11128
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.1.0
We've added support for viewing errors and warnings information in the
RM/NM/ATS web UI in Dal. To enable the functionality, the appender EWMA has to
be added to the logger. This can be achieved by appending it to the
YARN_ROOT_LOGGER environment variable(if the current value is "INFO,RFA", it
should be set to "INFO,RFA,EWMA".
