Subject [jira] Updated: (HADOOP-1320) Rewrite 'random-writer' to use '-reducer NONE'
Date Mon, 11 Jun 2007 10:45:28 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun C Murthy updated HADOOP-1320:
----------------------------------

    Attachment: HADOOP-1320_1_20070611.patch

RandomWriter now uses 'reducer {{NONE}}', and also extends {{ToolBase}} and hence options
such as {{test.randomwriter.bytes_per_map}} and {{map.output.compress}} can be set via command-line...
(phew! relief! :) )

> Post HADOOP-1216 the 'random-writer' is archaic in the sense that it uses custom code
to write data to dfs, this is now supported by the framework and doesn't make sense to reinvent
the wheel here.
