Question

刚开始使用Prediction.IO - 在执行pio训练时获得异常。我正在使用通用推荐模板。

Pio状态，pio-start-all工作正常，报告没有错误

似乎“Elasticsearch客户端找不到” - 但是在端口9200上可以很好地卷曲localhost。

是否有人知道所提供的错误信息是指什么？

Answer 1

<?php function add($a, $b){ return $a + $b; } ?>的{{1}} PredictionIO pio-env.sh目录中PredictionIO的默认配置已在/conf上运行ElasticSearch。如果您将其更新为port 9300，那么您的培训步骤是否成功？

Prediction.io - pio列车失败，但有例外
