IndexOutOfBoundsException in Kmeans

[Divya <di...@k2associates.com.sg>]

Hi,

 

I have an input file in XML format

I am successfully able to convert it into Sequence file and then to vectors

But when I am trying to run Kmeans 

Getting error - Exception in thread "main"
java.lang.IndexOutOfBoundsException: Index: 1, Size: 1

 

 

$ bin/mahout kmeans -i  D:/MahoutResult/Exalead/seq2sparse/tfidf-vectors -o
D:/MahoutResult/Exalead/Kmeans  -c D:/MahoutResult/Exalead

/Kmeans -k 10  -x 20 -ow -cl
