Log:
add HADOOP_OVERRIDE_CLASSPATH and HBASE_OVERRIDE_CLASSPATH

Author: pkhemani

Summary: for example yesterday we ran into an issue wehre the MR task  wanted to use codec-1.4.jar instead of codec-1.3.jar and we had to turn off provsioning etc. to be able to get codec-1.3.jar out of the classpath.

Test Plan: ran these scripts without arg. That verifies the syntax of the change.
