ArrayIndexOutOfBoundsException #5
Description
I got the following exception error when I run hadoop mr:
Sampling started

Here is the code snippet causing exception:
InputSampler.writePartitionFile(job, new InputSampler.IntervalSampler<Text, Text>(this.conf.getSampleProbability()));
It seems the input files are not found... I created 'input' directory, and put ntriples '.nt' files in it.
Any idea?
Best,
