[rest] SPNEGO-based authentication
----------------------------------
Key: HBASE-5050
URL: https://issues.apache.org/jira/browse/HBASE-5050
Project: HBase
Issue Type: Improvement
Components: rest, security
Reporter: Andrew Purtell
Currently the REST gateway can authenticate to a HBase cluster using a
preconfigured principal. This provides a limited form of secure operation where
one or more gateways can be deployed with distinct principals granting
appropriate levels of privilege, but the service ports must be protected
through network ACLs. This is at best a stopgap.
SPNEGO is the standard mechanism for Kerberos authentication over HTTP. Enhance
the REST gateway such that it provides this option, and issues requests to the
HBase cluster with the established context.
