我在HDP 2.6群集中启用了Kerberos Security,在启用Kerberos之前安装了Kafka和Storm服务。
我正在运行的拓扑有kafka-spout,后跟hdfs-bolt。因此,使用内置的Kafka Spout摄取来自特定Kafka主题的CSV数据,然后使用内置的HDFS Bolt传输到HDFS目录。
我正面临一个错误: 未启用SIMPLE身份验证。可用:[TOKEN,KERBEROS]
代码:
Map<String, Object> map = new HashMap<String,Object>();
map.put("hdfs.keytab.file","/etc/security/keytabs/storm.headless.keytab");
map.put("hdfs.kerberos.principal","storm-hdp26ks@VSS.COM");
Config conf = new Config();
conf.put("hdfs.config", map);
conf.put(HdfsSecurityUtil.STORM_KEYTAB_FILE_KEY,"/etc/security/keytabs/storm.headless.keytab");
conf.put(HdfsSecurityUtil.STORM_USER_NAME_KEY,"storm-hdp26ks@VSS.COM");
conf.setNumWorkers(1);
HdfsBolt hdfsbolt = new HdfsBolt()
.withFsUrl(hdfsUrl)
.withFileNameFormat(fileNameFormat).withRecordFormat(recordFormat)
.withRotationPolicy(rotationPolicy).withSyncPolicy(syncPolicy).withConfigKey("hdfs.config");
StormSubmitter.submitTopology(topologyName, conf, builder.createTopology());
错误:
Thread-7-hdfs-bolt-executor[3 3] [ERROR]
org.apache.hadoop.security.AccessControlException:
SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS]
如果我需要对storm-hdfs连接器执行任何其他步骤/配置相关更改以使用Kerberos,请告诉我。
