我正在尝试在virtualBox ubuntu 16.04版本上安装Prediction.io。 以下配置为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
运行命令后
PredictionIO-0.12.0-incubating/dist/bin/pio status
获得低于输出

我是predict.io的新手，尝试通过参考安装手册 - https://predictionio.apache.org/install/install-sourcecode/
