[jira] Commented: (HADOOP-5731) IPC call can raise security exceptions when the remote node is running under a security manager

    [ https://issues.apache.org/jira/browse/HADOOP-5731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12794205#action_12794205 ] 

Steve Loughran commented on HADOOP-5731:
----------------------------------------

HADOOP-6452 is the root cause of the RMI-related stack trace. With that patch in, there is one less reason why you can't run Hadoop under a security manager if you so desire.
