Question

大家好我试图关注quick start of HBase并在本地文件系统上启动HBase（不使用HDFS）但是当我使用./hbase shell启动shell并输入“status”时我得到了zookeeper错误？！

hbase(main):001:0> status
14/01/07 12:44:48 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries
14/01/07 12:44:48 WARN zookeeper.ZKUtil: hconnection Unable to set watcher on znode (/hbase/hbaseid)
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid

//......... ect .....

这是我的配置文件（hbase-site.xml）

      By default this is set to localhost for local and pseudo-distributed modes

      this is the list of servers which we will start/stop ZooKeeper on.

有什么建议吗？

Answer 1

您的zookeeper仲裁名称必须是您计算机的主机名，并且还必须存在于/ etc / hosts文件中。在此之后尝试重新启动网络。

Answer 2

问题出在这里（在你的conf - conf/hbase-site.xml中）：

<name>hbase.zookeeper.quorum</name>
      <value>localhost</value>

错误＆＃34; ERROR zookeeper.RecoverableZooKeeper：3次重试后ZooKeeper存在失败＆＃34;表示您的zookeeper.quorum指令存在问题。或者在启动HBase shell之前，您可以使用以下命令验证ZKQuorum是否已启动：

$ jps

该命令将列出机器上的所有java进程，即可能的输出必须是：

62019 Jps
61098 HMaster        
61233 HRegionServer     
61003 HQuorumPeer

<强>解决方案：

在HBase目录中，首先停止HBase：

$ ./bin/stop-hbase.sh

如果你正试图找出独立的HBase＆＃39;示例 - 坚持示例中提供的最小conf：

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>file:///home/adio/workspace/hadoop/hbase/directories/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/adio/workspace/hadoop/hbase/directories/zookeeper</value>
  </property>
</configuration>

即。您的conf/hbase-site.xml应具有以上内容。

设置完成后，立即再次启动HBase：

$ ./bin/start-hbase.sh

在本地文件系统上独立HBase得到zookeeper错误？
