Subject [jira] [Created] (AMBARI-11128) Add EWMA to yarn log4j appenders in Dal
Date Thu, 14 May 2015 12:36:59 GMT
Andrew Onischuk created AMBARI-11128:

             Summary: Add EWMA to yarn log4j appenders in Dal
                 Key: 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".
