Problem:
The ALS.sql verification query fails. The view log (accessible from ) shows:
SQL-MR function failed: com.asterdata.ncluster.sqlmr.ClientVisibleException: An issue with Spark job was detected.
Solution: On the Hadoop Spark HDFS, issue this command:
hadoop fs -ls /tmp/ALSModel1
If that directory exists, delete it, using this command:
hadoop fs -rm -r /tmp/ALSModel1
Rerun the ALS.sql verification query.
