Devaraj Das updated HIVE-1696:
------------------------------
Attachment: hive-1696-4.patch
I renamed the "principal" to "kerberos_principal" in the thrift calls
introduced by this patch. Also this patch has only one getTokenStrForm method
in the shim (the implementation of the method already handles what the other
method was handling), and i put a detailed javadoc on that. This patch is
without the gen'ed code. Once I get a go-ahead on this patch, I will submit a
patch with the gen'ed code. Could this patch be quickly looked at please?

> As discussed in HIVE-842, kerberos authentication is only sufficient for
> authentication of a hive user client to the metastore. There are other cases
> where thrift calls need to be authenticated when the caller is running in an
> environment without kerberos credentials. For example, an MR task running as
> part of a hive job may want to report statistics to the metastore, or a job
> may be running within the context of Oozie or Hive Server.
> This JIRA is to implement support of delegation tokens for the metastore. The
> concept of a delegation token is borrowed from the Hadoop security design -
> the quick summary is that a kerberos-authenticated client may retrieve a
> binary token from the server. This token can then be passed to other clients
> which can use it to achieve authentication as the original user in lieu of a
> kerberos ticket.
