> Opened for Yaw Tan:
> I'm using the Madlib k-means CLOSEST COLUMN function to determine the Cluster
> ID for the data point

> Function:madlib.closest_column(double precision, double precision, regproc,
> text): Error converting an array w/ NULL values to dense format
> The fix is to ignore NULL values in the array.
