我是HBase的新手,我确定我安装正确。在我的终端上,我也能够启动hbase shell,但是即使是一个简单的create语句也会给我以下错误:
(注意:我正在尝试在独立模式下运行它)
WARN zookeeper.ZKUtil: hconnection Unable to set watcher on znode (/hbase/hbaseid)
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid

at org.apache.hadoop.hbase.zookeeper.ZKUtil.checkExists(ZKUtil.java:450)
at org.apache.hadoop.hbase.zookeeper.ClusterId.readClusterIdZNode(ClusterId.java:61)
........
另外,我只在eclipse中写了2行,然后尝试运行它,
public static void main(String[] args) throws MasterNotRunningException, ZooKeeperConnectionException {
// TODO Auto-generated method stub
Configuration config = HBaseConfiguration.create();
HBaseAdmin admin = new HBaseAdmin(config);
}
它给了我以下错误:
15/03/18 22:25:37 INFO zookeeper.ClientCnxn: Opening socket connection to server fe80:0:0:0:0:0:0:1%1/fe80:0:0:0:0:0:0:1%1:2181. Will not attempt to authenticate using SASL (Unable to locate a login configuration)

可能是什么问题?
我的/ etc / hosts文件为127.0.0.1 localhost。
我还有什么需要做或改变的吗?
最佳答案
http://hbase.apache.org/book.html#quickstart这是设置hbase的很好的文档。您可能会缺少一些配置。
