[jira] Created: (HADOOP-187) simple distributed dfs random data
writer & sort example applications
simple distributed dfs random data writer & sort example applications
---------------------------------------------------------------------
Key: HADOOP-187
URL: http://issues.apache.org/jira/browse/HADOOP-187
Project: Hadoop
Type: Test
Components: mapred
Versions: 0.1.1
Reporter: Owen O'Malley
Assigned to: Owen O'Malley
Fix For: 0.2
These are the examples/benchmark programs that I've been using to test Hadoop map/reduce with. The first is a program that runs 10 maps/node and each map writes 1 gig of random data to a dfs file as a SequenceFile of BytesWritable/BytesWritable.
The second uses the identity map and reduce to sort the data and write it out to dfs.
