Karthik Kambatla updated HADOOP-12451:
--------------------------------------
Attachment: HADOOP-12451-branch-2.1.patch
Simple patch that adds a check to see if HADOOP_HOME has already been set,
similar to how HADOOP_HDFS_HOME is handled.
[~cnauroth] - can you please review the patch since you know the latest details
on how to ensure it runs with cygwin?
> One should be able to set HADOOP_HOME outside as well
