--------------------------------------
Summary: Null handling in kmeans
Key: MADLIB-946
URL: https://issues.apache.org/jira/browse/MADLIB-946
Project: Apache MADlib
Issue Type: Bug
Components: Module: k-Means Clustering
Reporter: Frank McQuillan
Opened for Yaw Tan:
I'm using the Madlib k-means CLOSEST COLUMN function to determine the Cluster
ID for the data point
The error says
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.
