[jira] [Commented] (HADOOP-7489) Hadoop logs errors upon startup on
OS X 10.7
[ https://issues.apache.org/jira/browse/HADOOP-7489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13271034#comment-13271034 ]
Allen Wittenauer commented on HADOOP-7489:
------------------------------------------
Java has its own internal version of Kerberos. That version is very, very stupid in 1.6 and earlier when it comes to using naming services for auto-discovery of the realm and KDC information. You'll see similar weirdness even on non-OS X boxes when the krb5.conf doesn't explicitly list the realm information. The same configuration fix mentioned here applies there as well. This has been fixed in JRE 1.7. Allegedly.
