Subject [jira] Commented: (MAPREDUCE-1832) Support for file sizes less than 1MB in DFSIO benchmark.
Date Thu, 03 Jun 2010 19:08:53 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12875252#action_12875252
] 

Konstantin Boudnik commented on MAPREDUCE-1832:
-----------------------------------------------

+1 patch looks good. A nit (for a couple of places):
- instead of {{DFSConfigKeys.DFS_SUPPORT_APPEND_KEY}} instead of {{"dfs.support.append"}}

Other than that looking real good.

> Currently DFSIO benchmark allows to specify files sizes in 1MB increments. It would be
useful to be able to specify smaller sizes.
