mariakatosvich commented on HDFS-9276:
--------------------------------------

In long running applications, the tokens will be expired, so we must update the tokens.
TestBalancer and TestHttpServerLifecycle failures areunrelated and they pass on my local host.
Thanks

> 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 = "xxx@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

>               null

>           UserGroupInformation.getCurrentUser.addCredentials(creds1)

>           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}
