TAM-Lab opened a new issue, #7867: URL: https://github.com/apache/seatunnel/issues/7867
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened In my requirement, I need to sync data from one hdfs to another, for which I execute seatunnel using the following configuration, but an error is reported: Caused by: javax.security.auth.login.LoginException: Cannot locate KDC at com.sun.security.auth.module.Krb5LoginModule.attemptAuthentication(Krb5LoginModule.java:804) at com.sun.security.auth.module.Krb5LoginModule.login(Krb5LoginModule.java:617) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at javax.security.auth.login.LoginContext.invoke(LoginContext.java:755) at javax.security.auth.login.LoginContext.access$000(LoginContext.java:195) at javax.security.auth.login.LoginContext$4.run(LoginContext.java:682) at javax.security.auth.login.LoginContext$4.run(LoginContext.java:680) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.login.LoginContext.invokePriv(LoginContext.java:680) at javax.security.auth.login.LoginContext.login(LoginContext.java:587) at org.apache.hadoop.security.UserGroupInformation$HadoopLoginContext.login(UserGroupInformation.java:1924) at org.apache.hadoop.security.UserGroupInformation.doSubjectLogin(UserGroupInformation.java:1836) ... 17 more The krb5.conf specified in the seatunnel configuration file contains the right KDC configurations, but it looks like does not take effect. The program appears to have read the /etc/krb5.conf path file by default. After I change the content of /etc/krb5.conf to that of the krb5.conf file in the seatunnel configuration, the program runs normally. Question: The krb5_path configuration of source HdfsFile does not take effect. The program will only read the /etc/krb5.conf path file by default ### SeaTunnel Version SeaTunnel Version=2.3.7 ### SeaTunnel Config ```conf source { HdfsFile { path = "/user/hive/test/dt=2024-10-15" file_format_type = "parquet" fs.defaultFS = "hdfs://hadoop" hdfs_site_path = "/local/hadoop/hdfs-site.xml" krb5_path = "/local/kerberos/krb5.conf" kerberos_principal = "xxx" kerberos_keytab_path = "/local/kerberos/xxx.keytab" } } sink { HdfsFile { fs.defaultFS = "hdfs://hadoop" path = "/user/hive/test_result_table" tmp_path = "/tmp/seatunnel" file_format_type = "parquet" hdfs_site_path = "/local/hadoop2/hdfs-site.xml" have_partition = true partition_by = ["dt"] } } ``` ### Running Command ```shell /opt/soft/seatunnel/apache-seatunnel-2.3.7/bin/seatunnel.sh --config /config/hdfs-sync-data.conf -m local ``` ### Error Exception ```log Caused by: javax.security.auth.login.LoginException: Cannot locate KDC at com.sun.security.auth.module.Krb5LoginModule.attemptAuthentication(Krb5LoginModule.java:804) at com.sun.security.auth.module.Krb5LoginModule.login(Krb5LoginModule.java:617) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at javax.security.auth.login.LoginContext.invoke(LoginContext.java:755) at javax.security.auth.login.LoginContext.access$000(LoginContext.java:195) at javax.security.auth.login.LoginContext$4.run(LoginContext.java:682) at javax.security.auth.login.LoginContext$4.run(LoginContext.java:680) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.login.LoginContext.invokePriv(LoginContext.java:680) at javax.security.auth.login.LoginContext.login(LoginContext.java:587) at org.apache.hadoop.security.UserGroupInformation$HadoopLoginContext.login(UserGroupInformation.java:1924) at org.apache.hadoop.security.UserGroupInformation.doSubjectLogin(UserGroupInformation.java:1836) ... 17 more Caused by: KrbException: Cannot locate KDC at sun.security.krb5.Config.getKDCList(Config.java:1084) at sun.security.krb5.KdcComm.send(KdcComm.java:218) at sun.security.krb5.KdcComm.send(KdcComm.java:200) at sun.security.krb5.KrbAsReqBuilder.send(KrbAsReqBuilder.java:316) at sun.security.krb5.KrbAsReqBuilder.action(KrbAsReqBuilder.java:361) at com.sun.security.auth.module.Krb5LoginModule.attemptAuthentication(Krb5LoginModule.java:776) ... 31 more ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version jdk verson: 1.8 scala version 2.12 ### Screenshots _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
