------------------------------------
Summary: need mechanism for updating HDFS delegation tokens
associated with container launch contexts
Key: YARN-2648
URL: https://issues.apache.org/jira/browse/YARN-2648
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager, resourcemanager
Reporter: Jonathan Maron
During the launch of a container, the required delegation tokens (e.g. HDFS)
are passed to the launch context. If those tokens expire and the container
requires a restart the restart attempt will fail. Sample log output:
2014-10-06 18:37:28,609 WARN ipc.Client (Client.java:run(675)) - Exception
encountered while connecting to the server :
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken):
token (HDFS_DELEGATION_TOKEN token 124 for hbase) can't be found in cache
