      Description

      1.seqdirectory

      > mahout seqdirectory --input /user/hdfs/input/new1.csv --output
      > /user/hdfs/new1/seqdirectory --tempDir
      > /user/hdfs/new1/seqdirectory/tempDir

      2.seq2sparse

      > mahout seq2sparse --input /user/hdfs/new1/seqdirectory --output
      > /user/hdfs/new1/seq2sparse -wt tfidf

      3.kmeans

      > mahout kmeans --input /user/hdfs/new1/seq2sparse/tfidf-vectors
      > --output /user/hdfs/new1/kmeans -c /user/hdfs/new1/clusters/kmeans -x 3 -k 3 --tempDir /user/hdfs/new1/kmeans/tempDir

      and then error is occured

      Oozie Launcher failed, finishing Hadoop job gracefully

      Oozie Launcher ends

      Why kmeans driver can't make clusters in Hadoop with oozie system?
      In hadoop with not oozie system, it worked.
