Subject [jira] [Updated] (HDFS-1877) Create a functional test for file read/write
Date Thu, 19 May 2011 02:08:47 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

CW Chung updated HDFS-1877:
---------------------------

    Status: Patch Available  (was: Open)

Thanks for the suggestion. Here is another patch with the following improvements:
1. Use svn diff format 
2. System.out.println changed to LOG
3. Use sequential read rather than position read. Junit Test will therefore pass.
4. Removed unused import, declarations 
5. Test routine begin with name Test
6. Add parsing of command line option

> It would be a great to have a tool, running on a real grid, to perform function test
(and stress tests to certain extent) for the file operations. The tool would be written in
Java and makes HDFS API calls to read, write, append, hflush hadoop files. The tool would
be usable standalone, or as a building block for other regression or stress test suites (written
in shell, perl, python, etc).
