在本地单节点 Hadoop (HortonWorks) 上运行 PredictionIO 时，出现以下错误：

我应该如何在本地 Hadoop 安装上配置 HBase + Zookeepr？

在 Hbase 文件夹 /conf/hbase-site.xml，配置或添加：

<property>
  <name>hbase.zookeeper.property.dataDir</name>
  <value>YOUR ZOOKEEPER FOLDER</value>
</property>

例如：

<property>
  <name>hbase.zookeeper.property.dataDir</name>
  <value>/home/myname/zookeeper-3.4.6</value>
</property>
