Subject [jira] [Commented] (MAPREDUCE-4289) JobStatus.getReduceProgress() and JobStatus.getMapProgress() API's not giving any values
Date Fri, 08 Jun 2012 04:55:23 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291548#comment-13291548
] 

Devaraj K commented on MAPREDUCE-4289:
--------------------------------------

It is coming due to the hard-coded values in the below code,

{code:title=TypeConverter.java|borderStyle=solid}
public static JobStatus fromYarn(ApplicationReport application,
      String jobFile) {
    String trackingUrl = application.getTrackingUrl();
    trackingUrl = trackingUrl == null ? "" : trackingUrl;
    JobStatus jobStatus =
      new JobStatus(
          TypeConverter.fromYarn(application.getApplicationId()),
          0.0f, 0.0f, 0.0f, 0.0f,
          TypeConverter.fromYarn(application.getYarnApplicationState(), 
	  application.getFinalApplicationStatus()),
          org.apache.hadoop.mapreduce.JobPriority.NORMAL,
          application.getUser(), application.getName(),
          application.getQueue(), jobFile, trackingUrl, false
      );
    jobStatus.setSchedulingInfo(trackingUrl); // Set AM tracking url

{code} 

Here we don't have any provision to get the map and reduce progresses from RM. 

It doesn't look good to show these hard-coded values always to the user when they use JobClient.getAllJobs()
API.


Any thoughts?
