Subject [jira] Commented: (HADOOP-3327) Shufflinge fetachers waited too long between map output fetch re-tries
Date Fri, 02 May 2008 14:06:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593788#action_12593788
] 

Devaraj Das commented on HADOOP-3327:
-------------------------------------

Maybe till we have fetched 90% of the map outputs, we should do exponential backoff and after
that we switch to fixed time smaller backoffs. But in the case of multiple jobs running in
the cluster this policy might not be ideal (since the same tasktrackers might be serving outputs
from multiple jobs).
