> Fail fast rogue tasks that write too much to local disk
> -------------------------------------------------------
>
> Key: MAPREDUCE-6489
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6489
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: task
> Affects Versions: 2.7.1
> Reporter: Maysam Yabandeh
> Assignee: Maysam Yabandeh
> Attachments: MAPREDUCE-6489-branch-2.003.patch,
> MAPREDUCE-6489.001.patch, MAPREDUCE-6489.002.patch, MAPREDUCE-6489.003.patch
>
>
> Tasks of the rogue jobs can write too much to local disk, negatively
> affecting the jobs running in collocated containers. Ideally YARN will be
> able to limit amount of local disk used by each task: YARN-4011. Until then,
> the mapreduce task can fail fast if the task is writing too much (above a
> configured threshold) to local disk.
> As we discussed
> [here|https://issues.apache.org/jira/browse/YARN-4011?focusedCommentId=14902750&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14902750]
> the suggested approach is that the MapReduce task checks for BYTES_WRITTEN
> counter for the local disk and throws an exception when it goes beyond a
> configured value. It is true that written bytes is larger than the actual
> used disk space, but to detect a rogue task the exact value is not required
> and a very large value for written bytes to local disk is a good indicative
> that the task is misbehaving.
