Major 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.
