Andras Piros commented on OOZIE-2797:
-------------------------------------
[~rohini] thanks for the insights! Maybe a follow-up JIRA should be linked to
this one to be clear about what is the purpose of OOZIE-2797 and what will be
handled separately.
> Cancellation of Delegation Tokens

> Key: OOZIE-2797
> URL: https://issues.apache.org/jira/browse/OOZIE-2797
> Project: Oozie
> Issue Type: Bug
> Reporter: Satish Subhashrao Saley
> Assignee: Satish Subhashrao Saley
> Fix For: 5.0.0
>
> Attachments: OOZIE-2797-1.patch
>
>
> HCat delegation token does not get cancelled unless HCat cancels the token on
> its own after several days (i.e. depending on its configuration).
> Hive Action and Pig Action should cancel delegation token after completion.
> Currently, we can fix it by cancelling the tokens in finally block for Hive
> and Pig Action. I am putting patch for this.
> But, a cleaner solution would be to have a class specifying APIs for
> cancellation and for each type of token, there would be a separate
> implementation. We can do it for Oozie 5.0.0.
