NameNode HA is enabled. > 2. Kerberos is enabled. > 3. HDFS Delegation Token (not Keytab or TGT) is used to communicate with > NameNode. > 4. We want to update the HDFS Delegation Token for long running applicatons. > HDFS Client will generate private tokens for each NameNode. When we update > the HDFS Delegation Token, these private tokens will not be updated, which > will cause token expired. > This bug can be reproduced by the following program: > {code} > import java.security.PrivilegedExceptionAction > import org.apache.hadoop.conf.Configuration > import org.apache.hadoop.fs.{FileSystem, Path} > import org.apache.hadoop.security.UserGroupInformation > object HadoopKerberosTest { > def main(args: Array[String]): Unit = { > val keytab = "/path/to/keytab/xxx.keytab" > val principal = "x...@abc.com" > val creds1 = new org.apache.hadoop.security.Credentials() > val ugi1 = > UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, keytab) > ugi1.doAs(new PrivilegedExceptionAction[Void] { > // Get a copy of the credentials > override def run(): Void = { > val fs = FileSystem.get(new Configuration()) > fs.addDelegationTokens("test", creds1) > null > } > }) > val ugi = UserGroupInformation.createRemoteUser("test") > ugi.addCredentials(creds1) > ugi.doAs(new PrivilegedExceptionAction[Void] { > // Get a copy of the credentials > override def run(): Void = { > var i = 0 > while (true) { > val creds1 = new org.apache.hadoop.security.Credentials() > val ugi1 = > UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, keytab) > ugi1.doAs(new PrivilegedExceptionAction[Void] { > // Get a copy of the credentials > override def run(): Void = { > val fs = FileSystem.get(new Configuration()) > fs.addDelegationTokens("test", creds1) > null > } > }) > UserGroupInformation.getCurrentUser.addCredentials(creds1) > val fs = FileSystem.get( new Configuration()) > i += 1 > println() > println(i) > println(fs.listFiles(new Path("/user"), false)) > Thread.sleep(60 * 1000) > } > null > } > }) > } > } > {code} > To reproduce the bug, please set the following configuration to Name Node: > {code} > dfs.namenode.delegation.token.max-lifetime = 10min > dfs.namenode.delegation.key.update-interval = 3min > dfs.namenode.delegation.token.renew-interval = 3min > {code} > The bug will occure after 3 minutes. > The stacktrace is: > {code} > Exception in
