Boris Shkolnik updated HADOOP-6526:
-----------------------------------

    Attachment: HADOOP-6526-1.patch

fixed release warning for krb5.conf
javadoc and javac warnings are for "warning: sun.security.krb5.Config is Sun proprietary API and may be removed in a future release
     [exec]     [javac] import sun.security.krb5.Config; "

leaving it as is.

> We need a configurable mapping from full user names (eg. omalley@APACHE.ORG) to local user names (eg. omalley). For many organizations it is sufficient to just use the prefix, however, in the case of shared clusters there may be duplicated prefixes. A configurable mapping will let administrators resolve the issue.
