-----------------------------
Summary: Register ClientToken MasterKey in SecretManager after it
is saved
Key: YARN-1214
URL: https://issues.apache.org/jira/browse/YARN-1214
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Jian He
Assignee: Jian He
Currently, app attempt ClientToken master key is registered before it is saved.
This can cause problem that before the master key is saved, client gets the
token and RM also crashes, RM cannot reloads the master key back after it
restarts as it is not saved. As a result, client is holding an invalid token.
We can register the client token master key after it is saved in the store.
