Yuxiang Chen updated HIVE-19276: -------------------------------- Attachment: HIVE-19276_hivemetastore.patch HIVE-19276_hiveclient.patch > Metastore delegation tokens should return non-empty service field in > delegation tokens > -------------------------------------------------------------------------------------- > > Key: HIVE-19276 > URL: https://issues.apache.org/jira/browse/HIVE-19276 > Project: Hive > Issue Type: Task > Components: Hive > Reporter: Yuxiang Chen > Assignee: Yuxiang Chen > Priority: Major > Attachments: HIVE-19276_hiveclient.patch, > HIVE-19276_hivemetastore.patch > > > Metastore does not set the token signature by default in the metastore > (returns an empty string), and thus the service field, which is assigned to > the value of token signature, would also be empty. This would cause problem > that the clients cannot retrieve the right token from the token file, using > this service field. > Metastore delegation tokens currently return an empty string in the > delegation token for the "service" field. The service field should be set to > something that meaningfully identifies the metastore/cluster, so clients can > find it in the token file. > Meanwhile, we also want to change the code on hive metastore to use metastore > uris as the service field when token signature is empty. However, to make the > changes effective, we also need to do similar modifications on the client > side, as we mentioned above. > Thus to do this, we need to add the following logic: > (1) On the client side, the client will first try to get token using the > current service field, if it gets nothing, we fallback to use > "hive.metastore.uris" as the service field and retry token selection. > (2) On the metastore side, if the current token signature is not empty, we > set the service field to be the value of token signature; otherwise, we use > hive.metastore.uris as the service field. > The patch is in attachments. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
