Hi, I run item recommemder base on Netflix, but it always fail for not enough local disk space. So, I cut the User Id to half(not user account but user Id),to reduce the temp data. Now, it finish but take 40 hours. The command like follow:
hadoop jar /app/mahout-distribution-0.5/core/target/mahout-core-0.5-job.jar org.apache.mahout.cf.taste.hadoop.item.RecommenderJob -Dmapred.map.tasks=196 -Dmapred.reduce.tasks=196 -Dmapred.input.dir=NetFlix_data_new -Dmapred.output.dir=output_netflix8 my hadoop cluster: 28 nodes 16G memory per node 8 core per node 250G local disk per node
