我通过$bash-c“$（curl-s）安装了predictioniohttps://install.prediction.io/install.sh)"
当我查看pio状态时，它会显示以下消息：

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

如中所述https://docs.prediction.io/resources/faq/，我尝试通过$~/predictionio/vendors/hbase-x.y.z/bin/start-hbase.sh启动hbase，但仍然存在相同的错误。
我还可以尝试哪些解决方案？我需要手动安装zookeeper吗(我以为快速安装已经安装了）。谢谢！

hbase apache-zookeeper predictionio

听起来hbase没有正确初始化。第一次尝试做 pio-stop-all 然后 pio-start-all ，然后再试一次 pio status 再一次。如果不行，那就快跑吧 pio-stop-all 再次，然后通过键入以下命令查找正在运行的hbase示例 ps aux | grep hbase ，并关闭正在运行的相应hbase示例（使用 kill -9 <PID> ). 输入后 pio-start-all 再说一次，你应该能跑了 pio status 没有前面提到的错误。
----编辑-----
因为你刚安装了predictionio，正在运行 pio-start-all 应该够了。但是，根据我的经验，如果您使用hbase，您可能会遇到这样一种情况：您必须如上所述手动终止进程。

预言io已经完全失去了阴谋和任何可行的产品，因为甲骨文购买了他们！什么都不管用了。。actionml端口也坏了。我建议开始寻找其他地方的ml工具包

睡眠时间（100？）取决于您的情况。”等待hbase启动10秒“并不总是足够长。我在启动脚本中尽可能晚地执行pio状态以节省时间（无需睡眠）。然后pio状态将始终成功。

我知道这是一个旧的职位，但写这个答案，如果有人访问这个职位，那么这可能是有帮助的。
检查您可能看到的hbase日志 Unexpected exception, exiting abnormally java.io.EOFException 这个例外至少在我的日志里。
遍历到vendors/hbase中zookeeper dir下的verion\u 2 dir
现在 ls -ltr 日志文件检查长度为0字节的最新文件。删除文件并重新启动服务，它应该可以正常工作。我昨天面对这个问题，这解决了我的问题。

可能太迟了，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>
