[jira] [Commented] (MAPREDUCE-5938) AM tracking URL & Shuffle port in nodemanager is binding to all IPs

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15048095#comment-15048095 ] 

Harsh J commented on MAPREDUCE-5938:
------------------------------------

Shouldn't the fix follow the usual configurable approach as with other binding properties in Hadoop? A property X that's set to 0.0.0.0 by default, but can be set to a hostname/IP if it needs to be limited. Provide the property's value as an InetAddress (with the port property) to the bind command.

The current patch would cause a limitation of those that already are relying on the wildcard feature today.
