Hi!
After upgrading to Mahout 0.10.1, I have a runtime exception in the following
Hadoop code in which I create the input matrix for performing SSVD:
// prepare output matrix
81: final Configuration conf = new Configuration();
83: SequenceFile.Writer writer = SequenceFile.createWriter(conf,
Writer.file(new Path(path + "/" +
outputFileName)),
Writer.keyClass(IntWritable.class),
Writer.valueClass(VectorWritable.class));
while in the console we have:
...
[Loaded org.apache.hadoop.util.StringInterner from
file:/Users/mihaidascalu/Dropbox%20(Personal)/Workspace/Eclipse/ReaderBenchDev/lib/Mahout/mahout-mr-0.10.1-job.jar]

Any suggestions? I tried adding guava-14.0.1.jar as dependency, but it did not
fix it
Thanks and have a great day!
