Subject [jira] Updated: (HADOOP-1192) Du command takes a noticable longer time to execute on a large dfs than the 0.11 release
Date Mon, 02 Apr 2007 20:47:32 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1192?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hairong Kuang updated HADOOP-1192:
----------------------------------

    Attachment: du.patch

The checksum patch did not overwrite the method getContentLength in DistributedFileSystem.
This leads to the use of the default slower version of getContentLength defined in FileSystem.
This patch fixed the du problem. It also fixed the dus problem by declaring the totalSize
to be long.

than the previous release. Another problem is that dus prints a negative value.
