Subject [jira] [Commented] (MAPREDUCE-3473) A single task tracker failure shouldn't result in Job failure
Date Thu, 22 Dec 2011 06:05:31 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13174636#comment-13174636

Sharad Agarwal commented on MAPREDUCE-3473:
-------------------------------------------

a single machine failure doesn't result in job to fail; thats the whole point of hadoop. smile.

we are missing the difference with *Task* and *TaskAttempt*.  A task gets 4 chances (task
attempts) by default to run before the job is declared failed. 

I think this issue can be resolved as Invalid.

> Currently some task failures may result in job failures. Eg a local TT disk failure seen
in TaskLauncher#run, TaskRunner#run, MapTask#run is visible to and can hang the JobClient,
causing the job to fail. Job execution should always be able to survive a task failure if
there are sufficient resources.
