my guess is that its not initialising the Configuration correctly since the spark master is by default local. My guess is that to read from HDFS you’d have to set up a Spark cluster and specify the master URL using the —master flag.
Else, set up a Spark on YARN deployment using CDH. Then specify the master as —yarn-cluster. That should also work. > On 14-Apr-2016, at 3:43 PM, Rohit Jain <rohitkjai...@gmail.com> wrote: > > Hello Nikaash > > I did this. > > /Users/rohitjain/Documents/apache-mahout-distribution-0.11.2/bin/mahout > spark-itemsimilarity -i hdfs://localhost:9000/spdemo.txt -o > hdfs://localhost:9000/spout/ --filter1 like -fc 1 -ic 2 > -D:spark.io.compression.codec=lzf > > but it throws this exception > > Exception in thread "main" java.lang.IllegalArgumentException: Wrong FS: > hdfs://localhost:9000/spdemo1.txt, expected: file:/// > > On Thu, Apr 14, 2016 at 3:41 PM, Nikaash Puri <nikaashp...@gmail.com> wrote: > >> Hi, >> >> You’d need to specify the complete path along with HDFS URI. for eg. >> hdfs://namenode:<port>/path/to/file. >> >> - Nikaash >>> On 14-Apr-2016, at 3:39 PM, Rohit Jain <rohitkjai...@gmail.com> wrote: >>> >>> Hey Nikaash, >>> >>> I ran this command but its working local files not for hadoop input file. >>> How to make it work on hadoop uri? >>> >>> /Users/rohitjain/Documents/apache-mahout-distribution-0.11.2/bin/mahout >>> spark-itemsimilarity -i spdemo.txt -o /spout --filter1 like -fc 1 -ic 2 >>> -D:spark.io.compression.codec=lzf >>> >>> On Thu, Apr 14, 2016 at 3:19 PM, Nikaash Puri <nikaashp...@gmail.com> >> wrote: >>> >>>> Cool.
