K Means Cluster Analysis - stuck at ~20%


I am running a flow utilizing the K means cluster analysis tools and they are stuck at 20% ad 24% respectively (please see image). No error has been logged, however there is a warning " K-Centroids Cluster Analysis (154) The invalid name has been replaced by X". What is causing the flow to be stuck and what does this warning mean?


Thank you!

@grftjw can you provide us with a sample dataset, or at least a description of the data?


The data is confidential, but for all means and purpose hopefully the table dimensions and fields types will suffice: There are 1M records and 50 fields (columns). The data is all binary or double.

Clustering 1 million records and 50 fields, to me it's not surprising that it seems stuck; it sounds like something that is computation extremely heavy.

I assume if you sample your data to say 25% of that and run off a few columns it's fine?

I think you need to look at ways you can reduce the 50 fields! It will be very hard to explain the variance when there are so many variables!
