Hello everyone,
I'm using Mahout Streaming K Means multiple times in a loop, every time
for same input data, and output path is always different. Concretely,
I'm increasing number of clusters in each iteration. Currently it is run
on a single machine.
A couple of times (maybe 3 of 20 runs) I
Seen this issue happen a few times before, there are few edge conditions
that need to be fixed in the Streaming KMeans code and you are right that
the generated clusters are different on successive runs given the same
input.
IIRC this stacktrace is due to BallKMeans failing to read any input

Suneel,
Thank you for your answer, this was rather strange to me.
The number of points is 942. I have multiple runs, in each run I have a
loop in which number of clusters is increased in each iteration and I
multiple that number by 3, since I'm expecting log(n) initial
centroids, before Ball
Heh u r data size is tiny indeed. One of the edge conditions I was
alluding to was the failures of this implementation on tiny datasets.
Do u see any output clusters? If so how many points?
possible to share ur dataset to troubleshoot ?

Yes it is small, but it is just a sample, so the dataset will probably
be much bigger. So you think that this was the problem? Will this
problem be avoided in case of larger dataset?
I think that there were no output clusters, as I remember. I'm sending
the dataset, if you want to take a look.
Here is the dataset.

Here is the dataset, I've just checked to be sure it is the right one.
