hbase shell報錯
Can't get master address from ZooKeeper; znode data == null master.HMaster: Failed to become active
ERROR [Thread-14] master.HMaster: Failed to become active master
Hmaster啓動一會就消失
log報錯

此處原因涉及到的配置文件有 hadoop的core-site.xml 以及hbase hbase-site.xml
如果你的這兩個配置文件都沒問題，那請再次仔細查看，如果還是起不了，那就請看/etc/hosts 這個配置文件的配置，
例如127.0.0.1 localhost
最後，啓動 star-hbase.sh 啓動之後進入報錯

網上看到大神的啓動方式
先啓動regionserver，在啓動HMaster。
在regionServer上./hbase-daemon.sh start regionserver
在master上執行：./bin/hbase-daemon.sh start master
