Hi, I'm new to Spark, Mahout. Just tried to run the spark-itemsimilarity but no luck.
Here is what I did. 1. clone git Mahout git project 2. run "mvn install" 3. set $MAHOUT_HOME to the project path 4. added $MAHOUT_HOME/bin to the PATH variable 5. download Spark, extract it to a dir 6. set $SPARK_HOME to the dir ..../spark-1.2.0-bin-hadoop2.4 7. run command "mahout spark-itemsimilarity -i ./mahout-input/order_item.tsv -o ./output -f1 purchase -f2 view -os -ic 2 -fc 1 -td ," Below is the output. It says "Exception in thread "main" com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'akka.event-handlers'" Any help or suggestion is highly appreciated. Thanks, Kevin -------------------------------------------------------------------------------------------------------------- MAHOUT_LOCAL is set, so we don't add HADOOP_CONF_DIR to classpath. log4j:WARN No appenders could be found for logger (org.apache.mahout.sparkbindings). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
