Subject [jira] Created: (CHUKWA-267) Collect shuffling information from userlogs/syslog
Date Thu, 28 May 2009 00:49:45 GMT
Collect shuffling information from userlogs/syslog
--------------------------------------------------

                 Key: CHUKWA-267
                 URL: https://issues.apache.org/jira/browse/CHUKWA-267
             Project: Hadoop Chukwa
          Issue Type: New Feature
          Components: data collection
    Affects Versions: 0.2.0
         Environment: Redhat EL 5.1, Java 6
            Reporter: Eric Yang
             Fix For: 0.1.2, 0.2.0


Hadoop uses a customized version of log4j appender (org.apache.hadoop.mapred.TaskLogAppender)
for tasks.  Shuffling information is written to userlogs/syslog by TaskLogAppender.  For chukwa
to collect shuffling information, we need to write a new TaskLogAppender to do this.
