Subject [jira] Updated: (HDFS-663) DFSIO for append
Date Fri, 09 Oct 2009 06:08:31 GMT

     [ https://issues.apache.org/jira/browse/HDFS-663?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Shvachko updated HDFS-663:
-------------------------------------

    Attachment: appendDFSIO-MR.patch
                appendDFSIO.patch

Two separate patches for 0.21 and HDFS-641 branches.
Some changes:
- I made testIO() run on MiniDFSCluster. So now it is really tested on hdfs  instead of local
file system.
- Changed usage.
- Turned on append in the configuration for the test.
- testIO()  prints stats after each of the three jobs.
