Hbase HDFS集成- Hbase母版未启动

Question

我已经配置了在虚拟盒上并行运行的linux发行版的两个节点集群。

两个linux发行版中/etc/host文件的内容如下所示

hduser@ubuntu-master:~$ cat /etc/hosts
192.168.56.103  Ubuntu-Master master
192.168.56.102  LinuxMint-Slave slave
10.33.136.219   inkod2lp00100.techmahindra.com inkod2lp00100


hduser@LinuxMint-Slave ~ $ cat /etc/hosts
192.168.56.103  Ubuntu-Master master
192.168.56.102  LinuxMint-Slave slave
10.33.136.219   inkod2lp00100.techmahindra.com inkod2lp00100

两个linux发行版中hbase-site.xml ( Location - /usr/local/hbase/conf)的内容如下-

hduser@ubuntu-master:~$ cat /usr/local/hbase/conf/hbase-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>

<property>
  <name>hbase.tmp.dir</name>
  <value>file:///usr/local/hbase/hbasetmp/hbase-${user.name}</value>
</property>

<property>
    <name>hbase.master</name>
    <value>Ubuntu-Master:16000</value>
    <description>The host and port that the HBase master runs at.</description>
</property>

  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://Ubuntu-Master:54310/hbase</value>
  </property>

<property>
  <name>hbase.cluster.distributed</name>
  <value>true</value>
</property>

<property>
  <name>hbase.zookeeper.quorum</name>
  <value>Ubuntu-Master,LinuxMint-Slave</value>
</property>

   <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>file:///usr/local/hbase/zookeeperdata</value>
  </property>

<property>
     <name>hbase.zookeeper.property.clientPort</name>
   <value>2222</value>
 </property>
</configuration>

hduser@LinuxMint-Slave ~ $ cat /usr/local/hbase/conf/hbase-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

<property>
  <name>hbase.tmp.dir</name>
  <value>file:///usr/local/hbase/hbasetmp/hbase-${user.name}</value>
</property>

<property>
<name>hbase.master</name>
<value>Ubuntu-Master:16000</value>
<description>The host and port that the HBase master runs at.</description>
</property>

  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://Ubuntu-Master:54310/hbase</value>
  </property>

<property>
  <name>hbase.cluster.distributed</name>
  <value>true</value>
</property>

<property>
  <name>hbase.zookeeper.quorum</name>
  <value>Ubuntu-Master,LinuxMint-Slave</value>
</property>


  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>file:///usr/local/hbase/zookeeperdata</value>
  </property>

<property>
     <name>hbase.zookeeper.property.clientPort</name>
   <value>2222</value>
 </property>

</configuration>

但是，当我在主节点中启动HBase服务时，每次没有启动HMaster时，在初始启动HMaster失败之后

请检查服务状态：

hduser@ubuntu-master:~$ jps

3793 SecondaryNameNode
5332 HQuorumPeer
4006 ResourceManager
4134 NodeManager
4883 JobHistoryServer
6286 Jps
3512 NameNode
3637 DataNode
5535 HRegionServer

hduser@LinuxMint-Slave ~ $ jps
2504 DataNode
3175 HQuorumPeer
2651 NodeManager
3681 Jps
3291 HRegionServer

在这里，HMaster服务的日志文件

Answer 1

我最近也有同样的问题。

克服它的方法很简单，但是危险的。

您肯定会丢失HDFS.上的所有数据。

你应该做以下几点：

1. 停止所有hadoop服务：stop-hbase.sh && stop-yarn.sh && stop-dfs.sh
2. 删除主机和从服务器上的所有HDFS数据，您可以在hadoop的/etc/hadoop/hdfs-site.xml中找到路径，在我的例子中，我必须删除的文件夹是/home/hadoop/hadoopdata/hdfs/namenode和/home/hadoop/hadoopdata/hdfs/datanode。

相反，您可以简单地删除两个服务器上的/home/hadoop/hadoopdata目录。

下面是您可能需要查找的配置文件的一部分：

    <property>
        <name>dfs.name.dir</name>
        <value>file:///home/hadoop/hadoopdata/hdfs/namenode</value>
    </property>

    <property>
        <name>dfs.data.dir</name>
        <value>file:///home/hadoop/hadoopdata/hdfs/datanode</value>
    </property>

1. 在主服务器上运行：hadoop namenode -format ( namenode部分可能与您不同)。
2. 在从服务器上运行：hadoop datanode -format (对于您来说，datanode部分可能再次不同)。
3. 启动hadoop和其他服务：start-dfs.sh && start-yarn.sh && start-hbase.sh。
