[jira] [Commented] (HADOOP-11990) DNS#reverseDns fails with a
NumberFormatException when using an IPv6 DNS server
[ https://issues.apache.org/jira/browse/HADOOP-11990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14547499#comment-14547499 ]
Benoit Sigoure commented on HADOOP-11990:
-----------------------------------------
After some more Googling, this appears to be a JDK bug: [JDK-6991580: IPv6 Nameservers in resolv.conf throws NumberFormatException|https://bugs.openjdk.java.net/browse/JDK-6991580]. Don't know if there's anything that can be done in {{DNS.java}} to workaround this bug.
