[jira] Commented: (HADOOP-3010) ConcurrentModificationException
from org.apache.hadoop.ipc.Server$Responder in JobTracker
[ https://issues.apache.org/jira/browse/HADOOP-3010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12584005#action_12584005 ]
Raghu Angadi commented on HADOOP-3010:
--------------------------------------
I would recommend this for 0.16.3. The fact that it is currently not harmful is secondary, I think.
