ASF GitHub Bot commented on HADOOP-18795:
-----------------------------------------
steveloughran opened a new pull request, #5821:
URL: https://github.com/apache/hadoop/pull/5821
Adds a class DelegationBindingInfo which contains binding info beyond just
the AWS credential list.
I would consider
* optional signer
* for the proposed bulk delete, optional factory for the operations
These things may be so interrelated that it makes sense to allow the DT
binding to dynamically create them all.
The binding class can be expanded when needed. Until then, all existing
implementations will work, as the new method
DelegationBindingInfo deploy(AbstractS3ATokenIdentifier
retrievedIdentifier)
falls back to the original methods.
