>
> 1. If an invalid Similarity Measure has been specified as input to the
> RowSimilarityJob, it presently throws a ClassCastException but still proceeds
> with executing all of the subsequent tasks - VectorNormalizer, Cooccurrences
> Mapper and UnSymmetrify Mapper. We should exit the process early without
> having to invoke all of the subsequent tasks (all of them fail anyways).
> 2. It would be nice to have an --overwrite option for the Command line
> interface which would delete the temp and output paths at the beginning of
> RowSimilarityJob execution, similar to what's being done in seq2sparse,
> seqdirectory. If I run RowSimilarityJob over and over again with different
> similarity measures, I should not be forced to delete my temp and output
> paths first prior to invoking the job.
