hadoop - hadoop 上的 Hbase 未在分布式模式下连接

Question

您好，我正在尝试在 HADOOP(hadoop-2.7.0) 上设置 HBASE(hbase-0.98.12-hadoop2)
Hadoop 在 localhost:560070 上运行，运行良好。

我的 hbase-site.xml 如下所示

<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>

当我启动 ./start-hbase.sh 时，我在日志文件中收到此错误。

Answer 1

java.net.ConnectException: Call From bredgelinux-desktop/127.0.1.1 to localhost:54310 failed on connection exception: java.net.ConnectException: Connection refused

如果您有环回 IP 地址，则会发生此错误。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。
