Hi, Some other folks from the Mahout community experienced the same error as mine (described in the previous email) and I have seen posts mentioning this problem but not the solution. If anyone (I bet, there is someone) was able to run the "spectralkmeans" on Mahout successfully, can you please share the steps. I really need it.
