- 我在 Windows 机器中有 HBase。
- 我尝试通过 java 程序从另一台 Windows 机器访问相同的内容。
- 结果与拒绝连接错误。
笔记:
- 我在 Linux 中尝试了同样的方法,效果很好。我在 Linux 机器中有 HBase 并通过 java 从 Windows 机器访问它。仅当我尝试从 Linux 或 Windows 访问 Windows HBase 时才会出现问题

Java代码:
HConnection connection=null;
Configuration config=HBaseConfiguration.create();
config.clear();
config.set("hbase.zookeeper.quorum","172.16.101.82");
config.set("hbase.zookeeper.property.clientPort","2181");
try {
connection=HConnectionManager.createConnection(config);
}
catch(Exception e)

try {
HTableInterface table=connection.getTable(TableName.valueOf("sample"));
}
catch(Exception e)
