Let's start with ol' good DFSIO test.
Test to run DFSIO write, append, and read. Includes parameters to change number of files from default 10, size of files from default 10MB, and to set number of cycles to more than 1.
Looks good. One comment. I don't think this line in README file is correct:
> User must make sure that the user home directory exists prior to running the test.
as DFSIO doesn't write log files into user home and all temp. files are going under /benchmark HDFS folder. So, please remove it.
The home directory is needed for mapreduce to function normally... the test writes .staging there.
Ah, right. My bad. +1 then!
Will commit the patch soon.
Committed to the master. Thanks Dasha!
