HBase的单节点集群详细启动步骤(分为Zookeeper自带还是外装)
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)。
