我们正在运行linux的azure v2云上测试hadoop ha群集。我们正在尝试切换到azure blob存储。我们不确定应该如何使用blob存储配置名称节点。我们得到以下错误：

我们不太确定如何使用azureblob配置名称节点，因为blob有效地移交了hdfs功能。我们在hdfs-site.xml中有标准的ha-name节点配置，并使用以下属性修改了core-site.xml以启用blob存储。

<property>
      <name>fs.AbstractFileSystem.wasb.impl</name>
      <value>org.apache.hadoop.fs.azure.Wasb</value>
    </property>

    <property>
      <name>fs.azure.account.key.OUR_STORAGE_ACCOUNT.blob.core.windows.net</name>
      <value>"OUR_KEY"</value>
    </property>

    <property>
      <name>fs.defaultFS</name>
      <value>wasb://blob-hdfs@OUR_STORAGE_ACCOUNT.blob.core.windows.net</value>
      <final>true</final>
    </property>

    <property>
      <name>fs.azure.page.blob.dir</name>
      <value>/datadir</value>
    </property>

    <property>
      <name>fs.azure.selfthrottling.read.factor</name>
      <value>1.000000</value>
    </property>

    <property>
      <name>fs.azure.selfthrottling.write.factor</name>
      <value>1.000000</value>
   <property>

我们在原始集群中的ha名称是：

<!--    <property>
    <name>fs.defaultFS</name>
    <value>hdfs://namenodeha</value>
  </property> -->

我们根本没碰过hdfs-site.xml。
我们不确定名称节点设置。原始设置中的两个名称节点可能是多余的，因为底层blob应该处理所有复制等。
有人能澄清一下吗？

为了使其工作，我们在hdfs-site.xml中缺少以下属性。

<property>
     <name>dfs.datanode.https.address</name>
     <value>0.0.0.0:50475</value>
  </property>

  <property>
    <name>dfs.namenode.https-address.namenodeha.nn1</name>
    <value>bd-azure-qa-nn1:50470</value>
  </property>

  <property>
    <name>dfs.namenode.https-address.namenodeha.nn2</name>
    <value>bd-azure-qa-nn2:50470</value>
  </property>

    <property>
    <name>dfs.journalnode.https-address</name>
    <value>0.0.0.0:8481</value>                                 :
  </property>

当然要有合适的主机名。
