Changes: [pranjan] MAHOUT-981, Added outlier removal option in method and CLI for KMeansDriver. [pranjan] MAHOUT-981, MAHOUT-983. Fixing test cases which fail intermittently. Build is passing on my machine ( even for the last commit ). Tried to identify all test cases, which can fail intermittently and fixed them. ------------------------------------------ [...truncated 6380 lines...] 12/03/17 19:19:55 INFO mapred.JobClient: Map input records=21578 12/03/17 19:19:55 INFO mapred.JobClient: Reduce shuffle bytes=0 12/03/17 19:19:55 INFO mapred.JobClient: Reduce output records=21578 12/03/17 19:19:55 INFO mapred.JobClient: Spilled Records=43156 12/03/17 19:19:55 INFO mapred.JobClient: Map output bytes=17337483 12/03/17 19:19:55 INFO mapred.JobClient: Combine input records=0 12/03/17 19:19:55 INFO mapred.JobClient: Map output records=21578 12/03/17 19:19:55 INFO mapred.JobClient: SPLIT_RAW_BYTES=150 12/03/17 19:19:55 INFO mapred.JobClient: Reduce input records=21578 12/03/17 19:19:55 INFO common.HadoopUtil: Deleting /tmp/mahout-work-hudson/reuters-out-seqdir-sparse-kmeans/tfidf-vectors 12/03/17 19:19:55 INFO input.FileInputFormat: Total input paths to process : 1 12/03/17 19:19:55 INFO mapred.JobClient: Running job: job_local_0007 12/03/17 19:19:55 INFO mapred.MapTask: io.sort.mb = 100 12/03/17 19:19:55 INFO mapred.MapTask: data buffer = 79691776/99614720 12/03/17 19:19:55 INFO mapred.MapTask: record buffer = 262144/327680 12/03/17 19:19:56 INFO mapred.MapTask: Starting flush of map output 12/03/17 19:19:56 INFO mapred.MapTask: Finished spill 0 12/03/17 19:19:56 INFO mapred.Task: Task:attempt_local_0007_m_000000_0 is done.
