Hi,
I am trying to build and train UR 0.7.0 with PredictionIO 0.12.0-incubating on
a local "Small HA Cluster" (http://actionml.com/docs/small_ha_cluster) using
Elasticsearch 5.5.2.
By following different steps of the how-to, I success to execute the "pio
build" command of U.R 7.0. But I am getting some errors on the following step
of "pio train".
Here are the principal errors:
...

Connection error (check network and/or proxy settings)- all nodes failed; tried
[[127.0.0.1:9200]]
The cluster Elasticsearch (aml-elasticsearch) is up, but is not listening on
localhost.
Here under is my config of ES 5.5.2
PIO_STORAGE_SOURCES_ELASTICSEARCH_TYPE=elasticsearch
PIO_STORAGE_SOURCES_ELASTICSEARCH_CLUSTERNAME=aml-elasticsearch
PIO_STORAGE_SOURCES_ELASTICSEARCH_HOSTS=aml-master,aml-slave-1,aml-slave-2
PIO_STORAGE_SOURCES_ELASTICSEARCH_PORTS=9200,9200,9200
PIO_STORAGE_SOURCES_ELASTICSEARCH_SCHEMES=http
PIO_STORAGE_SOURCES_ELASTICSEARCH_HOME=/usr/local/elasticsearch
Did somebody get this kind of error before? Any help or suggestion would be
appreciated.
Thanks,
