问题描述

我是新来的Apache Hadoop的。我安装了多节点集群，但我得到两个错误。我不知道什么样的错误，这些都是与他们为什么generated.I对错误很多一派，但我没能找出错误的产生背后的原因。

I am new to apache hadoop. I am installing the multi-node cluster but I am getting two errors. I am not aware about what kind of errors these are and why they have generated.I have googled alot about the errors but I was not able to find out the reason behind the error generation.

  Error:Could not find or load main class org.apache.hadoop.util.PlatformName

  Error: Could not find or load main class org.apache.hadoop.hdfs.server.datanode.DataNode

这两个错误是由于数据节点或奴隶产生的。我需要知道的那种错误的，因为产生的原因，以及如何解决这些问题。谢谢你。

Both the errors are generated due to the datanode or slaves. I need to know about the kind of errors, the reason for generation,and how to resolve them. Thank you.

推荐答案

变更文件夹，存放：
    hbase.zookeeper.property.dataDir

Change folder which stores: hbase.zookeeper.property.dataDir

例如：

sudo mkdir hb
chown hduser:hadoop /home/hduser/hb

和HBase的中-site.xml中更改此属性。

And in hbase-site.xml change this property

<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/hduser/hb/zookeeper</value>
</property>
