Subject [jira] Commented: (HADOOP-2342) create a micro-benchmark for measure local-file versus hdfs read
Date Fri, 18 Jan 2008 01:40:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12560191#action_12560191
] 

Chris Douglas commented on HADOOP-2342:
---------------------------------------

The patch no longer applies to trunk (AllTestDriver has new items).

* Using ToolBase/ToolRunner would pick up its functionality, including:
** It would be useful for the file size and buffer size to be configurable through the config/generic
options
** Noting the rep param in the usage might also be helpful
