hbase-env.sh

export HBASE_OPTS="-XX:+UseConcMarkSweepGC"

【问题讨论】：

您是否尝试通过命令行运行，如果是，则需要添加以下 export HADOOP_CLASSPATH=`/usr/bin/hbase classpath` 。这是我需要在 linux 中输入的内容，我不知道关于 mac
它不适合我
quorum=localhost:2181..这是错误的。您需要将仲裁指定为机器的主机名。您的集群无法连接到 zookeeper
@Jijo，这是独立模式，所以 localhost 应该没问题
我认为hbase应该在独立模式下启动自己的zookeeper。

标签： hbase

【解决方案1】：

在命令行上尝试 jps 命令以确定您的服务是否正在运行你应该在那里看到 Zookeeper、HBMaster 和 HBRegionServer

然后我会摆脱

<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/var/zookeeper</value>
  </property>

如果您没有它，则默认为安全值，并且您的 ZK 可能会与此路径混淆。特别是您不清楚是否使用PC的MAC，您都提到了。物理路径在 PC 上使用 C:\xxx\ 符号，但在 mac 和 linux 上使用 file:///xxxxx/。

【解决方案2】：

我也收到了这个错误。我发现即使shell启动了并不代表你有服务器在运行，你仍然需要手动运行start-hbase.sh来启动服务器。

【解决方案3】：

HBase 独立启动它自己的 zookeeper（如果你运行 `start-hbase.sh），但如果它无法启动或继续运行，其他需要的 hbase 守护程序将无法工作。

确保在hbase-site.xml 文件中明确设置接口lo0 的属性：

<property>
  <name>hbase.zookeeper.dns.interface</name>
  <value>lo0</value>
</property>

<property>
  <name>hbase.regionserver.dns.interface</name>
  <value>lo0</value>
</property>

<property>
  <name>hbase.master.dns.interface</name>
  <value>lo0</value>
</property>

我发现，特别是当我的 wifi 开启时，如果这些条目丢失，zookeeper 会申请启动。
