使用spark独立集群部署预测

标签： apache-spark predictionio

我使用官方Recommendation作为测试。 我成功地完成了这些步骤：

  1. 事件服务器安装在docker容器中。（已成功）
  2. 配置eventdata，元数据和所有东西都存储在mysql中。（成功）
  3. 火车＆amp;在另一个docker容器中部署服务器。（成功）
  4. 安装在另一个容器中的spark独立群集。（已成功）
  5. 创建新应用。（成功）
  6. 导入足够的eventdata。（已成功）

    7. 当我按照以下方式训练和部署时，就像文档中描述的那样：

    pio train
pio deploy

    但是当我使用spark cluster，训练和部署如下时，train没问题（新模型已存储在mysql中），但deploy不成功。

    pio train -v engine.json -- --master spark://predictionspark:7077 --executor-memory 2G --driver-memory 2G --total-executor-cores 1
pio deploy -v engine.json --feedback --event-server-ip predictionevent --event-server-port 7070 --accesskey Th7k5gE5yEu9ZdTdM6KdAj0InDrLNJQ1U3qEBy7dbMnYgTxWx5ALNAa2hKjqaHSK -- --master spark://predictionspark:7077 --executor-memory 2G --driver-memory 2G --total-executor-cores 1

    所有日志：

    我不知道为什么。

    更多： 我没有使用安装在另一个docker容器上的独立集群，而是使用train＆amp; deploy服务器（@ user2906838 mentioned）在同一个容器上启动了一个带有spark的本地集群，它已成功完成。 我不明白为什么会这样。我无法使用当地的火花，这很奇怪。

    更多：

    / tmp文件夹，在两种不同的情况下，文件大小不同。

    success image failed image

    更多：

    这很有趣。我在spark-worker容器中找到了模型数据。

    spark-worker image

答案 0 :(得分：0)

step-deploy取决于在file：// tmp或hdfs：// tmp中写入的step-train数据。
