InterruptedException with MeanShiftCanopyDriver

[Neil Chaudhuri]

I am running MeanShiftCanopyDriver as a MR job on a Hadoop cluster, and I am 
getting the following exception after numerous cluster files are generated:

java.lang.InterruptedException: Mean Shift Iteration failed on input 
clusters/clusters-0
at 
org.apache.mahout.clustering.meanshift.MeanShiftCanopyDriver.runIterationMR(MeanShiftCanopyDriver.java:412)

org.apache.mahout.clustering.meanshift.MeanShiftCanopyDriver.buildClustersMR(MeanShiftCanopyDriver.java:353)

at 
org.apache.mahout.clustering.meanshift.MeanShiftCanopyDriver.run(MeanShiftCanopyDriver.java:165)

The method call, which happens to be wrapped in a Riffle-annotated class within 
a Cascading flow, is as follows:

MeanShiftCanopyDriver.run(
                    configuration,
                    inputDirectoryPath,
                    outputDirectoryPath,
                    new CosineDistanceMeasure(),
                    0.05,
                    0.01,
                    0.0001,
                    25,
                    false,
                    true,
                    false);

I know this isn't much to go on, but can you provide any hints as to what the 
cause of the issue might be?

Thanks.
