问题一:使用自己搭建的zookeeper集群而不使用hbase自带的zookeeper解决办法?
首先:在hbase-env.sh中修改如下参数:

屏蔽hbase自带的zookeeper
问题二:通过start-abase.sh启动hbase集群发现从节点报如下错误:

出现该问题的原因:因为整个集群时间没有统一,导致master连接slave超时,所以导致从节点的HRegionServer进程没有正常启动,
解决办法:
1⃣️.在hbase-site.xml文件中 修改增加 ,将时间改大点
<property>
<name>hbase.master.maxclockskew</name>
<value>150000</value>
</property>
2⃣️.修改日期
date -s 11/23/2013
修改时间
date -s 15:14:00
检查硬件(CMOS)时间
clock -r
这个修改在系统重启后就失效了,因此为了将这个时间永久生效,需要将修改的时间写入CMOS。
clock -w
最后,关闭所有hbase集群的进程,重启启动,需要注意的一点是,在启动hbase集群前,先自己手动启动zookeeper集群
