ERROR: Can't get master address from ZooKeeper; znode data == null 一定注意这只是问题的第一层表象,真的问题是:
File /hbase/.tmp/hbase.version could only be replicated to 0 nodes instead of minReplica
网上很多都是叫用两种方式解决
- stop/start 重启hbase
- 格式化 hdfs namenode -format,不能随随便便就格式话hadoop的namenode
按照上述方式试一两个小时找问题,没有找到,最后问题就在每个应用的日志里藏着
Hbase中启动中很多异常的坑会遇到,但是请一定不要慌,坑多是因为我们对她不熟悉,我找了一上午的错误例子,在今年5月份我记得我可以启动单机的hbase hadoop zookeeper,由于我的阿里云服务器要用作别用,我就关闭了三个应用,9月我再次启动时,就不能启动了。

我打开hbase hadoop zookeeper 三者中data缓存文件,里面还是5月份的数据,比较坑就是每次重启都不自己覆盖以前的文件的么。这里就以后不要用kill 去关掉线程了
[root@app hbase-1.2.0-cdh5.10.0]# cd data/tmp/
重新启动 hbase hadoop zookeeper 进入 hbase shell命令客户端
[root@app bin]# ./hbase shell 2018-09-22 11:12:00,809 INFO [main] Configuration.deprecation: hadoop.native.lib is deprecated.

最后强调一下jps 查看最近启动的进程中是不是全部启动,我这里是单机版的,仅供参考。
