我在独立模式下运行hadoop上的hbase。我已经成功安装了hadoop,zookeeper和hbase,但是在hbase中master没有启动。下面是我的hbase-site.xml

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/kumar/hdata/zookeeper</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.clientPort</name>
    <value>2181</value>
  </property>
</configuration>

我已经启动了hadoop和zookeeper服务:

start-all.sh
zkServer.sh start
start-hbase.sh

以及我在jps命令中得到的进程

2133 DataNode
1974 NameNode
2679 NodeManager
2365 SecondaryNameNode
3917 QuorumPeerMain
2527 ResourceManager
3935 Jps

hbase shell已成功启动,但当我在shell中运行任何命令(如“list”)时,我发现以下错误:

ERROR: KeeperErrorCode = NoNode for /hbase/master

之后我试着用下面的命令运行master

hbase master start

我得到以下错误:

此外,我没有得到任何回应,为本地hbase网址

hbase有一个内置的zookeeper示例,仅用于开发环境,并且在默认情况下,当您通过命令启动hbase时 start-hbase.sh 它也会启动zookeeper守护进程。错误是因为您已经启动了使用该端口的独立zookeeper 2181 . 当您启动hbase时,它会尝试启动它的内置zookeeper-in端口 2181 ,它也得到了错误!
如果要使用独立的zookeeper组件,请首先编辑该文件 hbase-env.sh 并添加行: export HBASE_MANAGES_ZK=false (您还可以在文件中搜索hbase\u manages\u zk变量并将其设置为 false ). 因此,现在当您启动hbase时,它只启动hbase守护进程,而不再启动zookeeper。记住,应该在hbase之前启动zookeeper守护程序。
