Question

我在两个ubuntu虚拟机之上安装了hadoop多节点集群。

在下一步中，我尝试在此虚拟集群上安装HBase。但是，当我使用start-hbase.sh运行HBase时，尽管HMaster已在主计算机和从计算机上正确运行，但是HRegionServer在主计算机上没有运行。

hbase-env.sh文件内容：

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export HBASE_OPTS="$HBASE_OPTS -XX:+UseConcMarkSweepGC"
export HBASE_MANAGES_ZK=false

hbase-site.xml文件内容：

<configuration>
    <property>
            <name>hbase.rootdir</name>
            <value>hdfs://machine-a:54310/hbase</value>
    </property>
    <property>
            <name>hbase.zookeeper.property.dataDir</name>
            <value>/usr/local/zookeeper</value>
    </property>
    <property>
            <name>hbase.cluster.distributed</name>
            <value>true</value>
    </property>
    <property>
            <name>hbase.zookeeper.property.clientPort</name>
            <value>2181</value>
    </property>
    <property>
            <name>hbase.zookeeper.quorum</name>
            <value>machine-a</value>
    </property>
</configuration>

zoo.cfg文件内容：

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/zookeeper
clientPort=2181

正在运行的动物园管理员：

Answer 1

尝试启动hbase时，出现了类似的日志。当我查看主日志时，可能会看到以下内容：

2020-05-25 16：18：20,529错误[master / VB-hbase：16000：becomeActiveMaster] master.HMaster：*****正在中止master vb-hbase，16000,1590403688901：未处理的异常。开始关机。 ***** java.lang.IllegalStateException：过程WAL依赖于在组件故障期间进行hsync进行正确操作的能力，但是基础文件系统不支持这样做。请检查'hbase.procedure.store.wal.use.hsyn c'的配置值，以设置所需的鲁棒性级别，并确保'hbase.wal.dir'的配置值指向可以提供文件系统的挂载。

然后我跟随steps here

显然，可能没有直接链接到错误的直接链接，因为我们在启动过程中记录了无效变量，而主服务器没有出现，因为我仍然可以看到错误，但到目前为止一切正常。

安装HBase后，HMaster进程未在hadoop多节点群集上运行
