Subject [jira] Commented: (PIG-1280) Add a pig-script-id to the JobConf of all jobs run in a pig-script
Date Wed, 05 May 2010 20:11:31 GMT

    [ https://issues.apache.org/jira/browse/PIG-1280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12864482#action_12864482

Richard Ding commented on PIG-1280:
-----------------------------------

There have been several similar requests (on adding new Pig properties to MR job) since this
Jira was filed. Here are a compilation of those properties:

* _pig.script.id_
* _pig.script_     (the Pig script generates this job)
* _pig.launcher.host_ (the host/IP of the machine on which the Pig script is executed)
* _pig.command.line_ (the Pig command line arguments of this script)
* _pig.input.dirs_ (comma separated input directory list of this job)
* _pig.output.dirs_ (comma separated output directory list of this job)
* _pig.version_

> It would be very useful for tools like gridmix if pig could add a 'pig-script-id' to
all Map-Reduce jobs spawned by a single pig-script. Potentially we could use this to re-construct
the DAG of jobs in gridmix and so on.
