Saikat Kanjilal commented on MAHOUT-940:
----------------------------------------

Paritosh, 
I'm assuming OOM means out of memory, is that correct?   So to be clear is the solution to this to use the ClusteredOutputProcessor instead of the ClusterDumper?  I will research code and move forward with an implementation.  Will ask questions if I get stuck,

> Current implementation of ClusterDumper puts clusters and related vectors in map. This generally results in OOM.
> Since ClusterOutputProcessor is availabale now. The ClusterDumper will at first process the clusteredPoints, and then write down the clusters to a local file. 
> The inability to properly read the clustering output due to ClusterDumper facing OOM is seen too often in the mailing list. This improvement will fix that problem.
