----------------------------------
Summary: Correctly cache delegation tokens in KMSClientProvider
Key: HADOOP-13127
URL: https://issues.apache.org/jira/browse/HADOOP-13127
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.6.1
Reporter: Xiao Chen
Assignee: Xiao Chen
In the initial implementation of HADOOP-10770, the authToken is updated with
delegation tokens during {{KMSClientProvider#addDelegationTokens }} in the
following line:
{code}
Token<?> token = authUrl.getDelegationToken(url, authToken, renewer);
{code}
HADOOP-11482 is a good fix to handle UGI issue, but has a side effect in the
following code:
{code}
public Token<?> run() throws Exception {
// Not using the cached token here.. Creating a new token here
// everytime.
return authUrl.getDelegationToken(url,
new DelegationTokenAuthenticatedURL.Token(), renewer, doAsUser);
}
{code}
IIUC, we should do {{setDelegationToken}} on the authToken here to cache it.
