下面是我使用kerberos连接到hbase的代码:
Configuration conf = HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum", "20.20.100.1");
conf.set("hbase.zookeeper.property.clientPort", "2181");
final String USER_KEY = "appuser.principal";
final String KEYTAB_KEY = "appuser.keytab.filename";
final String Key_user = Config.getProperties().getString("kerberos_keyuser");
final String Key_tab = Config.getProperties().getString("kerberos_keytab");
conf.set("hadoop.security.authentication", "kerberos");
conf.set("hbase.security.authentication", "kerberos");
conf.set(USER_KEY, Key_user);
conf.set(KEYTAB_KEY, Key_tab);
SecurityUtil.login(conf, KEYTAB_KEY, USER_KEY);
Connection connection = ConnectionFactory.createConnection(conf);
try (Table table = connection.getTable(TableName.valueOf("newssentiment:test"))) {
Scan scan = new Scan();
ResultScanner scanner = table.getScanner(scan);
Iterator<Result> iterator = scanner.iterator();
System.out.println();
while(iterator.hasNext()) {
System.out.println(iterator.next());
}
}
catch (Exception e){
System.out.print(e.getMessage());
}
HBaseAdmin.checkHBaseAvailable(conf);
connection.close();
System.out.println("HBase is running!");
但我有以下错误:
org.apache.hadoop.security.UserGroupInformation - PriviledgedActionException as:u8000 (auth:SIMPLE) cause:java.io.IOException: Failed to specify server's Kerberos principal name
org.apache.hadoop.hbase.ipc.AbstractRpcClient - Exception encountered while connecting to the server : java.io.IOException: Failed to specify server's Kerberos principal name
org.apache.hadoop.security.UserGroupInformation - PriviledgedActionException as:u8000 (auth:SIMPLE) cause:java.io.IOException: java.io.IOException: Failed to specify server's Kerberos principal name
同样的代码可以在linux上成功运行,但在windows上总是失败。

只要替换一下
SecurityUtil.login(conf, KEYTAB_KEY, USER_KEY);
与为简单起见,您可以按以下方式编写代码:
如果以上代码成功运行,您可以用变量替换固定值。
