Subject [jira] Created: (HADOOP-213) add/change TestDFSIO command line arguments
Date Fri, 12 May 2006 19:06:08 GMT
add/change TestDFSIO command line arguments
-------------------------------------------

         Key: HADOOP-213
         URL: http://issues.apache.org/jira/browse/HADOOP-213
     Project: Hadoop
        Type: Improvement

  Components: dfs  
    Reporter: Yoram Arnon
 Assigned to: Konstantin Shvachko 
    Priority: Minor


TestDFSIO would benefit from the follwing changes on the command line:

1. allow a "-dfs <dfs>" option, to specify which dfs to test. Just like the hadoop dfs
command.
2. allow a "-jt <job tracker>" option, to specify a job tracker. Just like the hadoop
job command.
3. allign the file size units with the dfs block size. Using MB (2^20) when the dfs uses 10^6
skews the results a bit.
4. add a "-replication <replication>" option, to specify files' replication factor.
