节点 /hbase 不在 ZooKeeper 中

Question

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

  ERROR client.HConnectionManager$HConnectionImplementation - The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

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

Answer 1

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>
