Question

我正在尝试按照these说明在本地设置PredictionIO。

不幸的是我无法让它发挥作用。当我尝试安装模板或运行“pio status”时，我收到错误消息，指出PredictionIO无法连接到elasticsearch：

[ERROR] [Console$] Unable to connect to all storage backends successfully. The following shows the error message from the storage backend.
[ERROR] [Console$] None of the configured nodes are available: [] (org.elasticsearch.client.transport.NoNodeAvailableException)
[ERROR] [Console$] Dumping configuration of initialized storage backend sources. Please make sure they are correct.
[ERROR] [Console$] Source Name: ELASTICSEARCH; Type: elasticsearch; Configuration: HOME -> /Users/tomasz/Documents/PredictionIO/apache-predictionio-0.10.0-incubating/PredictionIO-0.10.0-incubating/vendors/elasticsearch-1.4.4, HOSTS -> localhost, PORTS -> 9200, TYPE -> elasticsearch

我的pio-env.sh文件设置如下：

PIO_STORAGE_REPOSITORIES_METADATA_NAME=pio_meta
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

PIO_STORAGE_SOURCES_ELASTICSEARCH_TYPE=elasticsearch
PIO_STORAGE_SOURCES_ELASTICSEARCH_HOSTS=localhost
PIO_STORAGE_SOURCES_ELASTICSEARCH_PORTS=9200
PIO_STORAGE_SOURCES_ELASTICSEARCH_HOME=$PIO_HOME/vendors/elasticsearch-1.4.4

PIO_STORAGE_SOURCES_LOCALFS_TYPE=localfs
PIO_STORAGE_SOURCES_LOCALFS_PATH=$PIO_FS_BASEDIR/models

PIO_STORAGE_SOURCES_HBASE_TYPE=hbase
PIO_STORAGE_SOURCES_HBASE_HOME=$PIO_HOME/vendors/hbase-1.0.0

任何帮助都将不胜感激。

当我在PredictionIO版本0.11.0孵化时使用Elasticsearch 5.4.x时遇到了这个问题。它在我使用Elasticsearch 1.7.x

时起作用了

无法使用Localhost上的PredictionIO和Elasticsearch成功连接到所有存储后端
