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].
> Security uses proprietary Sun APIs

> Key: HADOOP-7211
> URL: https://issues.apache.org/jira/browse/HADOOP-7211
> Project: Hadoop Common
> Issue Type: Improvement
> Components: security
> Reporter: Eli Collins
> Assignee: Luke Lu
>
> 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.
