Subject [jira] Commented: (HADOOP-4787) TestTrackerBlacklistAcrossJobs fails randomly
Date Tue, 09 Dec 2008 04:39:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12654698#action_12654698

Amareshwari Sriramadasu commented on HADOOP-4787:
-------------------------------------------------

Chris, for the tracker to get blacklisted by a job, it should fail mapred.max.tracker.failures
times. Eariler this configuration was set to 1 at cluster level, which was ignored by job.
And it was waiting for 4 failures (default value) to get blacklisted. I moved it to job-level
in the patch. So, now it fails once, it will get blacklisted by job.
