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？

请您参考如下方法:

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>
