我通过$ bash -c "$(curl -s https://install.prediction.io/install.sh )"安装了 PredictionIO

当我执行pio status时，它显示以下消息：

[INFO] [Console$] Inspecting PredictionIO...

正如https://docs.prediction.io/resources/faq/中所建议的，我尝试通过$ ~/PredictionIO/vendors/hbase-xyz/bin/start-hbase.sh启动 HBase ，但仍然存在相同的错误。

我可以尝试哪些其他解决方案？我需要手动安装zookeeper吗？（我认为快速安装已经安装了它）。谢谢！

It sounds like HBase hasn't been initialized properly. First try doing pio-stop-all and then pio-start-all, and then try pio status again. If that doesn't work, then go ahead and run pio-stop-all again, and then look for a running instance of HBase by typing in the following command ps aux | grep hbase, and shut down the appropriate instance of HBase that is running (use kill -9 <PID>). After typing in pio-start-all again, you should be able to run pio status without the fore mentioned error.

----EDIT-----

Since you just installed PredictionIO, running pio-start-all should suffice. However, in my experience, if you are using HBase you may run into a situation where you have to kill the process manually as stated above.

自从甲骨文收购它们以来，Prediction-IO 已经完全失去了情节和任何可行的产品！什么都没有了。actionML 端口也坏了。我建议开始在其他地方寻找 ML-Toolkit

根据您的情况，睡眠几秒钟（100？）。“等待 10 秒让 HBase 启动”并不总是足够长。我在启动脚本中尽可能晚地执行 pio status 以节省时间（无需睡眠）。那么 pio status 将永远成功。

可能为时已晚，但对我有用。

在您的供应商中找到 hbase-site.xml

更改 /vendors/hbase-1.2.6/conf/hbase-site.xml

<configuration>
<property>
      <name>hbase.rootdir</name>
      <value>file:///home/{your-user}/PredictionIO/vendors/hbase-1.2.6/data</value>
   </property>
   <property>
     <name>hbase.zookeeper.property.dataDir</name>
     <value>/home/{your-user}/PredictionIO/vendors/hbase-1.2.6/zookeeper</value>
   </property>
</configuration>

我知道这是一篇旧帖子，但是如果有人访问此帖子，请写下此答案，那么这可能会有所帮助。

检查 hbase 日志，您可能会Unexpected exception, exiting abnormally java.io.EOFException在我的日志中看到此异常。

遍历vendors/hbase中zookeeper目录下的verion_2目录

现在ls -ltr日志文件检查 0 字节长度的最新文件。删除文件并重新启动服务，它应该可以正常工作。我昨天遇到了这个问题，这解决了我的问题。
