Subject Spark MLLIB Decision Tree - ArrayIndexOutOfBounds Exception
Date Tue, 21 Oct 2014 09:42:52 GMT
Hi All, 

I am trying to run the spark example JavaDecisionTree code using some
external data set. 
It works for certain dataset only with specific maxBins and maxDepth
settings. Even for a working dataset if I add a new data item I get a
ArrayIndexOutOfBounds Exception, I get the same exception for the first case
as well (changing maxBins and maxDepth). I am not sure what is wrong here,
can anyone please explain this. 

Exception stacktrace:
