如何将Java Hadoop认证_hadoop3 Java客户端 Kerberos认证实现为高效安全的认证流程？

本文共计190个文字，预计阅读时间需要1分钟。

plaintext使用以下认证方法：Configuration config=new Configuration();

org.apache.hadoophadoop-hdfs3.1.1org.apache.hadoophadoop-common3.1.1org.apache.hadoophadoo

org.apache.hadoop

hadoop-hdfs

3.1.1

org.apache.hadoop

hadoop-common

3.1.1

org.apache.hadoop

hadoop-client

3.1.1

认证方法

Configuration config new Configuration();

config.set("fs.hdfs.impl", "org.apache.hadoop.hdfs.DistributedFileSystem");

config.set("dfs.client.block.write.replace-datanode-on-failure.policy", "NEVER");

//开始Kerberos认证

String krb5File "/etc/krb5.conf";

System.setProperty("java.security.krb5.conf", krb5File);

config.set("hadoop.security.authentication", "kerberos");

UserGroupInformation.setConfiguration(config);

try {

UserGroupInformation.loginUserFromKeytab(kerUser, keyPath);

} catch (IOException e) {

e.printStackTrace();

}

//结束Kerberos认证

URI uri new URI("hdfs://" host ":" port);

FileSystem.get(uri, config);
