Subject mahout spark-rowsimilarity error
Date Fri, 19 May 2017 01:14:30 GMT
Hi,

I am trying to research potential features to feed into the Universal
Recommendation engine by using the mahout command line interface.  I can
successfully run mahout spark-rowsimilarity
<https://mahout.apache.org/users/recommender/intro-cooccurrence-spark.html> on
up to about 500 rows of data. After that I get the error below:

INFO DAGScheduler: Job 7 failed: saveAsTextFile at
TextDelimitedReaderWriter.scala:294, took 1.110184 s
Exception in thread "main" org.apache.spark.SparkException: Job aborted due
to stage failure: Task 0 in stage 12.0 failed 1 times, most recent failure:
Lost task 0.0 in stage 12.0 (TID 24, localhost):
java.lang.IllegalArgumentException

I tried various cli options like below but get the same error:

mahout spark-rowsimilarity --maxObservations 500000 -sem 6g -ma "local[4]"
--input items.csv --output /tmp/output

Any suggestions would be most helpful.

I cross posted on Stack Overflow here

Thanks
