----------------------------------
> Integrate user-experience for hbase-client
> ------------------------------------------
>
> Key: HBASE-26667
> URL: https://issues.apache.org/jira/browse/HBASE-26667
> Project: HBase
> Issue Type: Sub-task
> Reporter: Josh Elser
> Assignee: Andor Molnar
> Priority: Major
> Fix For: HBASE-26553
>
>
> Today, we have two mechanism in order to get the tokens needed to
> authenticate:
> # Kerberos, we rely on a Kerberos ticket being present in a well-known
> location (defined by JVM properties) or via programmatic invocation of
> UserGroupInformation
> # Delegation tokens, we rely on special API to be called (our mapreduce API)
> which loads the token into the current UserGroupInformation "context" (the
> JAAS PrivilegedAction).
> The JWT bearer token approach is very similar to the delegation token
> mechanism, but HBase does not generate this JWT (as we do with delegation
> tokens). How does a client provide this token to the hbase-client (i.e.
> {{ConnectionFactory.getConnection()}} or a {{UserGroupInformation}} call)? We
> should be mindful of all of the different "entrypoints" to HBase ({{{}hbase
> ...{}}} commands, {{java -cp}} commands, Phoenix commands, Spark comands,
> etc). Our solution should be effective for all of these approaches and not
> require downstream changes.
