Description

This issue was formerly titled "Select and document a platform-independent scripting language for use in Hadoop environment" and was discussed in the common-dev@ threads "[PROPOSAL] introduce Python as build-time and run-time dependency for Hadoop and throughout Hadoop stack" and "[VOTE] introduce Python as build-time and run-time dependency for Hadoop and throughout Hadoop stack".

In that discussion the community consensus rejected the idea of using Python as a cross-platform scripting language.

It is now proposed to follow up Allen's suggestions below about simplifying the use of scripts in Hadoop, bring more functionality into core code, and try to leave us with only trivial usages of scripting that can readily be maintained in as many platform-specific scripting languages as necessary.
