Steve Loughran moved HADOOP-12497 to HDFS-9276: ----------------------------------------------- Component/s: (was: ha) (was: fs) ha fs Key: HDFS-9276 (was: HADOOP-12497) Project: Hadoop HDFS (was: Hadoop Common) > Failed to Update HDFS Delegation Token for long running application in HA mode > ------------------------------------------------------------------------------ > > Key: HDFS-9276 > URL: https://issues.apache.org/jira/browse/HDFS-9276 > Project: Hadoop HDFS > Issue Type: Bug > Components: fs, ha > Reporter: Liangliang Gu > > The Scenario is as follows: > 1. 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: > 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 > } > }) > } > } > To reproduce the bug, please set the following configuration to Name Node: > dfs.namenode.delegation.token.max-lifetime = 10min > dfs.namenode.delegation.key.update-interval = 3min > dfs.namenode.delegation.token.renew-interval = 3min > The bug will occure after 3 minutes. > The stacktrace is: > Exception in thread "main" > org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken): > token (HDFS_DELEGATION_TOKEN token 330156 for test) is expired > at org.apache.hadoop.ipc.Client.call(Client.java:1347) > at org.apache.hadoop.ipc.Client.call(Client.java:1300) > at > org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:206) > at com.sun.proxy.$Proxy9.getFileInfo(Unknown Source) > at > org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getFileInfo(ClientNamenodeProtocolTranslatorPB.java:651) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:606) > at > org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:186) > at > org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:102) > at com.sun.proxy.$Proxy10.getFileInfo(Unknown Source) > at org.apache.hadoop.hdfs.DFSClient.getFileInfo(DFSClient.java:1679) > at > org.apache.hadoop.hdfs.DistributedFileSystem$17.doCall(DistributedFileSystem.java:1106) > at > org.apache.hadoop.hdfs.DistributedFileSystem$17.doCall(DistributedFileSystem.java:1102) > at > org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) > at > org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:1102) > at org.apache.hadoop.fs.FileSystem.resolvePath(FileSystem.java:747) > at > org.apache.hadoop.hdfs.DistributedFileSystem$15.<init>(DistributedFileSystem.java:726) > at > org.apache.hadoop.hdfs.DistributedFileSystem.listLocatedStatus(DistributedFileSystem.java:717) > at > org.apache.hadoop.fs.FileSystem.listLocatedStatus(FileSystem.java:1780) > at org.apache.hadoop.fs.FileSystem$5.<init>(FileSystem.java:1842) > at org.apache.hadoop.fs.FileSystem.listFiles(FileSystem.java:1839) > at HadoopKerberosTest6$$anon$2.run(HadoopKerberosTest6.scala:55) > at HadoopKerberosTest6$$anon$2.run(HadoopKerberosTest6.scala:32) > at java.security.AccessController.doPrivileged(Native Method) > at javax.security.auth.Subject.doAs(Subject.java:415) > at > org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1491) > at HadoopKerberosTest6$.main(HadoopKerberosTest6.scala:32) > at HadoopKerberosTest6.main(HadoopKerberosTest6.scala) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:606) > at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
