Balu Vellanki created FALCON-952:
------------------------------------

             Summary: If hadoop home is set, use $HADOOP_HOME to set falcon classpath
                 Key: FALCON-952
                 URL: https://issues.apache.org/jira/browse/FALCON-952
             Project: Falcon
          Issue Type: Bug
          Components: build-tools
    Affects Versions: 0.6
            Reporter: Balu Vellanki
            Assignee: Balu Vellanki
             Fix For: 0.7


Falcon uses `hadoop classpath` to find the classpath to required hadoop jars. It is possible to have multiple versions of hadoop installed on falcon node. To pick the right version of hadoop, the following is suggested. 

1)  If HADOOP_HOME is set, use `${HADOOP_HOME}/bin/hadoop classpath`. 
2) Else If `which hadoop` is not empty, use `hadoop classpath`
