Subject [jira] [Commented] (HADOOP-7211) Security uses proprietary Sun APIs
Date Fri, 06 Apr 2012 05:38:37 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7211?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248084#comment-13248084

Todd Lipcon commented on HADOOP-7211:

I don't think this JIRA should be marked as duplicate, because clearly HADOOP-6941 wasn't
thoroughly tested. As soon as I tried running a cluster with a 2NN I found that it didn't
work. So I'm skeptical that there isn't more work to do...

> The security code uses the KrbException, Credentials, and PrincipalName classes from
sun.security.krb5 and Krb5Util from sun.security.jgss.krb5. These may disappear in future
Java releases. Also Hadoop does not compile using jdks that do not support them, for example
with the following IBM JDK.
