Subject [jira] [Commented] (HADOOP-9082) Simplify scripting usages so that parallel platform-dependent scripts are simple to maintain
Date Thu, 31 Jul 2014 22:17:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14081586#comment-14081586

Allen Wittenauer commented on HADOOP-9082:
------------------------------------------

It's interesting reading this thread in light of my own attempt to greatly improve the bash
code in HADOOP-9902.

> 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.
