[jira] Commented: (MAPREDUCE-1982) [Rumen] TraceBuilder's output shows jobname as NULL for jobhistory files with valid jobnames

["Amar Kamat (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1982?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12893560#action_12893560 ] 

Amar Kamat commented on MAPREDUCE-1982:
---------------------------------------

Also {{TraceBuilder}} extracts various job configuration properties like 
  # job-name
  # queue-names
  # mapred-child task jvm settings etc 

from job's conf. So this bug is seen only when there is a jobconf present in the jobhistory folder.

> {{TraceBuilder}} fails to extract configuration properties (like job-name) from the job-conf if the job-conf has the properties stored using the deprecated keys.
