[jira] Commented: (HADOOP-5304) job.xml should have high replication factor by default

    [ https://issues.apache.org/jira/browse/HADOOP-5304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675772#action_12675772 ] 

Vinod K V commented on HADOOP-5304:
-----------------------------------

Setting this would help ameliorate JobTracker's behaviour in situations like HADOOP-5285, as JT would now have more datanodes to download job.xml from.

> job.xml is set the default replication factor of 3 by the JobClient. The same config file is accessed from the DFS by JT as well as all the TTs. Hence it should be set a high replication factor say 10, just like the job.jar.
