Subject [jira] Commented: (HADOOP-4784) Need value for Running, Completed and Failed maps and reduces for a job.
Date Fri, 05 Dec 2008 13:43:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12653777#action_12653777
] 

Amar Kamat commented on HADOOP-4784:
------------------------------------

Looking at the code it looks like these counts are maintained in {{JobInProgress}}. We can
probably get away with the (re)computation in {{jobdetails.jsp}}. Also other job level info
like _num-maps_/_num-reduces_ should also be provided to the client via {{JobProfile}}. {{TaskReports}}
doesnt pass any information whether a TIP is {{WAITING, RUNNING, SUCCEEDED, KILLED, FAILED}}.
These info at the user side makes a lot of difference and saves time spent in parsing the
jsp files.

> Currently there is no JobClient call which gives information for Running, Completed and
Failed maps and reduces for a job. Only way to get this is to parse jobdetails.jsp.
