Subject [jira] Updated: (MAPREDUCE-1825) jobqueue_details.jsp and FairSchedulerServelet should not call finishedMaps and finishedReduces when job is not initialized
Date Tue, 08 Jun 2010 18:47:12 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1825?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Scott Chen updated MAPREDUCE-1825:
----------------------------------

    Description: 
JobInProgress.finishedMaps() and finishedReduces() are synchronized. They are called from
jobqueue_details.jsp and FairSchedulerServelet which iterates through all jobs. If any job
is in initialization, these pages don't come up until the initialization finishes.

See [comment|https://issues.apache.org/jira/browse/MAPREDUCE-1354?focusedCommentId=12834139&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12834139]
for more details

  was:
JobInProgress.finishedMaps() and finishedReduces() are synchronized. They are called from
jobqueue_details.jsp and FairSchedulerServelet which iterates through all jobs. If any job
is in initialization, we should skip the job until the initialization finishes.
