My main concern here was that HADOOP_HOME is deprecated since hadoop 0.23.
So I was hoping it could actually function as documented.
FWIW, I found this bug[1] that addresses exactly this issue. The attached
patch makes HADOOP_HOME not required and auto-detects hadoop from the path.
This seems to h
Hm. Yeah I tried out with a few version 0.7 -> 0.9 and seems like they all
do. May be we should just update the documentation then?

We are using Hive 0.7.1 and there HADOOP_HOME must be exported so that it
is available as environment variable.

Thanks for your reply nitin.
Ok. So you mean we always need to set HADOOP_HOME irrespective of "hadoop"
is on the path or not. Correct?
Little confused because that contradicts what's mentioned here[1].

This is not a bug.
even if hadoop was path, hive does not use it.
Hive internally uses HADOOP_HOME in the code base. So you will always need
to set that for hive.
Where as for HADOOP clusters, HADOOP_HOME is deprecated but hive still
needs it.
Don't know if that answers your question
Thanks,
Nit
