I'm trying to install Prediction.io on virtualBox ubuntu 16.04 version. Following is configured pio-env.sh
PIO_STORAGE_REPOSITORIES_METADATA_NAME=pio_metadata
PIO_STORAGE_REPOSITORIES_METADATA_SOURCE=ELASTICSEARCH
PIO_STORAGE_REPOSITORIES_EVENTDATA_NAME=pio_event
PIO_STORAGE_REPOSITORIES_EVENTDATA_SOURCE=HBASE
PIO_STORAGE_REPOSITORIES_MODELDATA_NAME=pio_model
PIO_STORAGE_REPOSITORIES_MODELDATA_SOURCE=LOCALFS
After running command
PredictionIO-0.12.0-incubating/dist/bin/pio status
Getting below output
