Log:
commit d220ff57e0cda48b7a369ac6c1d611dc8207184c
Author: Devaraj Das <ddas@yahoo-inc.com>
Date:   Fri Jul 16 10:04:51 2010 -0700

    HADOOP:6818 from https://issues.apache.org/jira/secure/attachment/12449618/hadoop-6818-2.patch
    
    +++ b/YAHOO-CHANGES.txt
    +    HADOOP-6818. Provides a JNI implementation of Unix Group resolution. The
    +    config hadoop.security.group.mapping should be set to
    +    org.apache.hadoop.security.JniBasedUnixGroupsMapping to enable this
    +    implementation. (ddas)
    +
    +    the system classes during job submission and in task launches. Two things
    +    need to be done in order to use this feature -
    +    (1) mapreduce.user.classpath.first : this should be set to true in the
    +    jobconf, and, (2) HADOOP_USER_CLASSPATH_FIRST : this is relevant for job
    +    submissions done using bin/hadoop shell script. HADOOP_USER_CLASSPATH_FIRST
    +    should be defined in the environment with some non-empty value
    +    (like "true"), and then bin/hadoop should be executed. (ddas)
