--------------------------------
Summary: Add log for ZooKeeperTokenStore
Key: HIVE-27564
URL: https://issues.apache.org/jira/browse/HIVE-27564
Project: Hive
Issue Type: Improvement
Reporter: lvyanquan
Assignee: lvyanquan
Attachments: picture 1.png
when use zookeeper to store DelegationTokenIdentifier, we use
{code:java}
TokenStoreDelegationTokenSecretManager.encodeWritable(tokenIdentifier) {code}
to encode message of tokens, like picture1.png
However, when this token was removed, error message will display
DelegationTokenIdentifier only, then we have no idea about whether this path is
still existed and when the path in zookeeper was created and deleted.
{code:java}
public byte[] retrievePassword(DelegationTokenIdentifier identifier) throws
InvalidToken {
DelegationTokenInformation info = this.tokenStore.getToken(identifier);
if (info == null) {
throw new InvalidToken("token expired or does not exist: " +
identifier);
}
// must reuse super as info.getPassword is not accessible
synchronized (this) {
try {
super.currentTokens.put(identifier, info);
return super.retrievePassword(identifier);
} finally {
super.currentTokens.remove(identifier);
}
}
} {code}
So, I try to add so log about the lifecycle of the tokenPath.
