[jira] Commented: (HADOOP-4011) shuffling backoff 5 minutes despite the whole cluster is idle

    [ https://issues.apache.org/jira/browse/HADOOP-4011?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650897#action_12650897 ] 

Jothi Padmanabhan commented on HADOOP-4011:
-------------------------------------------

This should no longer be seen as we reverted back HADOOP-3327. 
Runping, can you confirm if you have observed similar behavior in recent times? As per the current code, the retry should be almost immediate (4 seconds)
