+1, +1, +1 (some comments inline) -----Original Message----- From: mfo...@hortonworks.com [mailto:mfo...@hortonworks.com] On Behalf Of Matt Foley Sent: Saturday, November 24, 2012 12:13 PM To: common-dev@hadoop.apache.org Subject: [VOTE] introduce Python as build-time and run-time dependency for Hadoop and throughout Hadoop stack
For discussion, please see previous thread "[PROPOSAL] introduce Python as build-time and run-time dependency for Hadoop and throughout Hadoop stack". This vote consists of three separate items: 1. Contributors shall be allowed to use Python as a platform-independent scripting language for build-time tasks, and add Python as a build-time dependency. Please vote +1, 0, -1. 2. Contributors shall be encouraged to use Maven tasks in combination with either plug-ins or Groovy scripts to do cross-platform build-time tasks, even under ant in Hadoop-1. Please vote +1, 0, -1. >>> I believe 1&2 in combination make a total sense. I ported a few scripts to >>> Python, and thus far, it showed to be up to the task and satisfy the >>> cross-platform requirements. In my option, it is also important to agree on >>> the version, as I've run into some breaking changes in version 3+. 3. Contributors shall be allowed to use Python as a platform-independent scripting language for run-time tasks, and add Python as a run-time dependency. >>> This is a great aspirational goal! Maintaining two sets of scripts would be >>> a real challenge. Please vote +1, 0, -1. Note that voting -1 on #1 and +1 on #2 essentially REQUIRES contributors to use Maven plug-ins or Groovy as the only means of cross-platform build-time tasks, or to simply continue using platform-dependent scripts as is being done today. Vote closes at 12:30pm PST on Saturday 1 December. --------- Personally, my vote is +1, +1, +1. I think #2 is preferable to #1, but still has many unknowns in it, and until those are worked out I don't want to delay moving to cross-platform scripts for build-time tasks. Best regards, --Matt
