[jira] Created: (MAHOUT-419) Convert decomposer code to Hadoop 0.20
API
Convert decomposer code to Hadoop 0.20 API
------------------------------------------
Key: MAHOUT-419
URL: https://issues.apache.org/jira/browse/MAHOUT-419
Project: Mahout
Issue Type: Improvement
Components: Math
Affects Versions: 0.3
Reporter: Danny Leshem
org.apache.mahout.math.hadoop classes (MatrixMultiplicationJob, TimesSquaredJob, TransposeJob) all use the deprecated Hadoop API. In the spirit of MAHOUT-167 and MAHOUT-143, I suggest converting them to Hadoop's 0.20 API.
The reason I'm raising this now is that this code no longer runs on my Hadoop 0.22-SNAPSHOT cluster (not sure why really - it was running fine about a month ago, but after updating to the latest Mahout trunk a few days ago the code throws "java.lang.RuntimeException: Error in configuring object" at MapTask.runOldMapper).
Also, the documentation at https://cwiki.apache.org/MAHOUT/dimensionalreduction.html is no longer accurate - the command line parameters have changed (even without the new arguments from MAHOUT-308). This is partly due to using the new argument parser which receives the input/output directories differently.

I agree, and purely for housekeeping purposes I want to roll this into mega-issue MAHOUT-167.
