Subject [jira] [Created] (AMBARI-1135) Workflow log4j appender expects DAG not to change
Date Tue, 08 Jan 2013 20:04:13 GMT
Billie Rinaldi created AMBARI-1135:

             Summary: Workflow log4j appender expects DAG not to change
                 Key: AMBARI-1135
             Project: Ambari
          Issue Type: Bug
          Components: client
            Reporter: Billie Rinaldi
             Fix For: 1.2.0

Each job may contain DAG information, but the log4j appender ignores it for all but the first
job in the workflow.  This is a problem because Pig may generate multiple independent DAGs
for a single script, e.g. if "exec" is called in the middle of the script.  The log4j appender
needs to merge together the DAG information for all the jobs in a workflow instead of assuming
that the DAG won't change.
