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.
