Subject [jira] [Commented] (HADOOP-7211) Security uses proprietary Sun APIs
Date Fri, 06 Apr 2012 05:54:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7211?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248095#comment-13248095
] 

Devaraj Das commented on HADOOP-7211:
-------------------------------------

On HADOOP-6941, my aim was to make the hadoop code base compile with IBM's JDK, and ensure
that there is no regression with Oracle's. I had done testing of HDFS/MR with security enabled.
I didn't do the tests that would go through the SecurityUtil code path though (argh) [fixed
in HADOOP-8251].

> 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.
