Hudson commented on MAHOUT-294:
-------------------------------
Integrated in Mahout-Quality #276 (See
[https://hudson.apache.org/hudson/job/Mahout-Quality/276/])
MAHOUT-294: Added arguments to the DistributedLanczosSolver CLI so that
it can optionally launch the EigenVerificationJob. Added a new run() method with
additional arguments needed by EVJ. Added new unit tests of the CLI and adjusted
some of the cluster dumper tests to use the new run method. All tests run.
NOTE: this patch changes the semantics of the DLS --output argument: Formerly
it was the path to the output (raw) eigenvectors file. Now it is a path to an
output
directory in which a rawEigenvectors file will be written. If the EVJ is also
specified,
then the output directory will contain a cleanEigenvectors file in addition.
> Uniform API behavior for Jobs

> * Move AbstractJob to common and convert all the Driver classes to extend
> that.
> One suggestion is:
> AlgorithmParams params = ParamsBuilder.build().withParam("-i",
> input).withParam("-o", output)....
> MyAlgorithmn.runJob(params) throws ParameterMissingException;
> * Give uniform command-line parameters for various algorithms.
> e.g Currently distance measure is -d, -dm, -m at different places in
> clustering
> * Add a temp directory as a parameter

> and cleanup of Mahout API
