hadoop 上的 Hbase 未在分布式模式下连接
Hbase on hadoop not connecting on distrubuted mode
您好，我正在尝试在 HADOOP(hadoop-2.7.0) 上设置 HBASE(hbase-0.98.12-hadoop2)
Hadoop 运行 localhost:560070 运行 很好。
我的hbase-site.xml如下图
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>localhost</value>
</property>
<!-- <property>
<name>dfs.replication</name>
<value>1</value>
</property>-->
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
当我开始 ./start-hbase.sh 我在日志文件中收到这个错误。

如果您有环回 IP 地址，则会出现此错误。请按照以下步骤纠正此错误：
第 1 步： 从 /etc/hosts 中删除带有 127.0.1.1 的行。
第 2 步： 重新启动您的 hadoop 和 hbase 进程。
我猜（因为我之前在数据节点日志中看到过类似的错误）你已经删除了你的数据节点数据目录并重新启动它。
尝试关闭 HDFS（datanodes 和 namenode），删除 namenode 和 datanode 数据目录，启动集群并格式化 namenode。
现在 Hbase 在 hadoop 上 运行。无法访问目录 'datanode' 和 'namenode'。可能是因为这个 Hadoop 无法访问这些目录。我在这些目录和名称节点格式上执行了 chmod 777 并重新启动了系统。现在我的 habse 在端口 61000 上是 运行 。谢谢大家的回复。

如果您有环回 IP 地址，则会出现此错误。请按照以下步骤纠正此错误：
第 1 步： 从 /etc/hosts 中删除带有 127.0.1.1 的行。
第 2 步： 重新启动您的 hadoop 和 hbase 进程。
我猜（因为我之前在数据节点日志中看到过类似的错误）你已经删除了你的数据节点数据目录并重新启动它。
尝试关闭 HDFS（datanodes 和 namenode），删除 namenode 和 datanode 数据目录，启动集群并格式化 namenode。
现在 Hbase 在 hadoop 上 运行。无法访问目录 'datanode' 和 'namenode'。可能是因为这个 Hadoop 无法访问这些目录。我在这些目录和名称节点格式上执行了 chmod 777 并重新启动了系统。现在我的 habse 在端口 61000 上是 运行 。谢谢大家的回复。
