[jira] Commented: (HADOOP-3619) DNS.getHosts triggers an ArrayIndexOutOfBoundsException in reverseDNS if one of the interfaces is IPv6

    [ https://issues.apache.org/jira/browse/HADOOP-3619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12794407#action_12794407 ] 

Steve Loughran commented on HADOOP-3619:
----------------------------------------

Once HADOOP-6056 is committed, this can be made a LATER, but perhaps tag it IPv6 so that when someone sits down to do the migrate, they will know the problems that will surface

> reverseDNS tries to split a host address string by ".", and so fails if ":" is the separator, as it is in IPv6. When it tries to access the parts of the address, a stack trace is seen.
