Hbase自带zookeeper路径

Posted 2023-04-08 柠檬芦荟加少冰

今天学习使用Hbase遇到报错：

ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

......

网上查到的结果都说要清理一下zookeeper的记录，但是用的是Hbase自带的zookeeper所以根本不知道要去哪清理，也找不到路径，费了好大劲终于找到了

路径：/tmp/hbase-用户名/zookeeper

注意这里是从根目录开始，不在hbase的目录里面。zookeeper的日志文件都在version2中，删除version2整个文件夹后报错就解决了

HBase的多节点集群详细启动步骤（3或5节点）（分为Zookeeper自带还是外装）

 

 

HBase的多节点集群详细启动步骤（3或5节点）分为：

　　1、HBASE_MANAGES_ZK的默认值是false（zookeeper外装）（推荐）

　　2、HBASE_MANAGES_ZK的默认值是true（zookeeper自带）

 

 

 

 

 

 

 

1、HBASE_MANAGES_ZK的默认值是false（推荐）

　　伪分布模式下,如(weekend110)
　　hbase-env.sh配置文档中的HBASE_MANAGES_ZK的默认值是true，它表示HBase使用自身自带的Zookeeper实例。但是，该实例只能为单机或伪分布模式下的HBase提供服务。

 

　　若是分布式模式，则需要配置自己的Zookeeper集群。如(HadoopMaster、HadoopSlave1、HadoopSlave2)
　　hbase-env.sh配置文档中的HBASE_MANAGES_ZK的默认值是true，它表示，分布式模式里，在启动HBase时，HBase将Zookeeper作为自身的一部分运行。进程变为HQuorumPeer。
　　hbase-env.sh配置文档中的HBASE_MANAGES_ZK的默认值是false，它表示，分布式模式里，需要，先提前手动，每个节点都手动启动Zookeeper，然后再在主节点上启动HBase时，进程变为HMaster（HadoopMaster节点）。

 

　　若，HBASE_MANAGES_ZK的默认值是false
1、则，直接在HadoopMaster机器上，先启动Hadoop，
2、在HadoopMaster、HadoopSlave1、HadoopSlave2机器上，分别手动一个一个得去，启动Zookeeper
3、在HadoopMaster机器上，再启动HBase即可。

 

　　1、则，直接在HadoopMaster机器上，先启动Hadoop，
