我试图在本文之后以独立模式部署Hbase:http://hbase.apache.org/book.html#quickstart .版本是0.92.1-cdh4.1.2
但是在尝试创建表时我遇到了这些错误:

是的,我确实搜索了很多.我发现一些信息ZooKeeper在3次重试后存在失败.可能是这个错误是因为zookeeper被停止了.但我不知道要重新启动它.我试着重新开始Hbase,thrift但仍然是这个问题.
这个命令ps axww | grep QuorumPeerMain给我以下输出:
6162 pts/2 S+ 0:00 grep --color=auto QuorumPeerMain
如果我重新启动系统,Hbase将开始工作.但我想要适当的解决方案. …
