> 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, security
> Affects Versions: 2.7.1
> Reporter: Liangliang Gu
> Assignee: Liangliang Gu
> Attachments: HDFS-9276.01.patch, HDFS-9276.02.patch,
> HDFS-9276.03.patch, HDFS-9276.04.patch, HDFS-9276.05.patch, debug1.PNG,
> debug2.PNG
>
>
> 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:
> {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 = "[email protected]"
> 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 thread "main"
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken):
> token (HDFS_DELEGATION_TOKEN token 330156 for test) is expired
