I'm getting an exception when I try to submit a job (through prediction.io, if you know it): [INFO] [Runner$] Submission command: /home/pio/PredictionIO/vendors/spark-1.5.1/bin/spark-submit --class io.prediction.tools.imprt.FileToEvents --files file:/home/pio/PredictionIO/conf/log4j.properties,file:/home/pio/PredictionIO/vendors/hbase-1.0.0/conf/hbase-site.xml --driver-class-path /home/pio/PredictionIO/conf:/home/pio/PredictionIO/vendors/hbase-1.0.0/conf file:/home/pio/PredictionIO/lib/pio-assembly-0.9.5.jar --appid 1 --input file:/home/pio/pio-ur/my_events.json --env PIO_STORAGE_SOURCES_HBASE_TYPE=hbase,PIO_ENV_LOADED=1,PIO_STORAGE_REPOSITORIES_METADATA_NAME=pio_meta,PIO_FS_BASEDIR=/home/pio/.pio_store,PIO_STORAGE_SOURCES_HBASE_HOME=/home/pio/PredictionIO/vendors/hbase-1.0.0,PIO_HOME=/home/pio/PredictionIO,PIO_FS_ENGINESDIR=/home/pio/.pio_store/engines,PIO_STORAGE_SOURCES_LOCALFS_PATH=/home/pio/.pio_store/models,PIO_STORAGE_SOURCES_ELASTICSEARCH_TYPE=elasticsearch,PIO_STORAGE_REPOSITORIES_METADATA_SOURCE=ELASTICSEARCH,PIO_STORAGE_REPOSITORIES_MODELDATA_SOURCE=LOCALFS,PIO_STORAGE_REPOSITORIES_EVENTDATA_NAME=pio_event,PIO_STORAGE_SOURCES_ELASTICSEARCH_HOME=/home/pio/PredictionIO/vendors/elasticsearch-1.4.4,PIO_FS_TMPDIR=/home/pio/.pio_store/tmp,PIO_STORAGE_REPOSITORIES_MODELDATA_NAME=pio_model,PIO_STORAGE_REPOSITORIES_EVENTDATA_SOURCE=HBASE,PIO_CONF_DIR=/home/pio/PredictionIO/conf,PIO_STORAGE_SOURCES_LOCALFS_TYPE=localfs[INFO] [Remoting] Starting remoting[INFO] [Remoting] Remoting started;

Thanks!
