[jira] Created: (HADOOP-6604) Improve HADOOP_HOME detection and handling in hadoop-config

Improve HADOOP_HOME detection and handling in hadoop-config
-----------------------------------------------------------

                 Key: HADOOP-6604
                 URL: https://issues.apache.org/jira/browse/HADOOP-6604
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 0.20.2
            Reporter: Chad Metcalf
            Assignee: Chad Metcalf
            Priority: Minor


If HADOOP_HOME is not set by the time hadoop-config is sourced we should try to guess it. Generally speaking hadoop-config.sh is in bin and HADOOP_HOME should generally be .. from there. Additionally we can do some verification of this guess by looking for jars in HADOOP_HOME.

------------------------------------------

This patch breaks if any hadoop core jar is in .. rather than the one we care about.
