Subject [jira] [Updated] (HBASE-4100) Authentication for REST clients
Date Wed, 21 Sep 2011 21:21:09 GMT

     [ https://issues.apache.org/jira/browse/HBASE-4100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Helmling updated HBASE-4100:
---------------------------------

    Attachment: HBASE-4100.patch

This patch implements step #1 for the REST server, allowing it to login from a keytab file
on startup.  The patch depends on a new method in the Strings class added in HBASE-4099.

Like the HBASE-4099 patch, this change is necessary for a REST server to work correctly with
the SecureRpcEngine from HBASE-2742, when using Kerberos authentication.

> Like Thrift, the REST gateway is not currently integrated into the authentication used
for HBase RPC.  Currently this means the REST gateway cannot even be used when HBase security
is active.
> For the REST gateway to be able to interoperate with HBase security:
> # the REST server needs to be able to login from a keytab on startup with its own server
principal
> # REST clients need to be able to authenticate security with the REST server
> # the REST server needs to be able to act as a trusted proxy for the original client
identities, so that the HBase authorization checks can be performed against the original client
request
> Like Thrift, implementing step #1 as a bare minimum would at least allow deploying a
REST server configured to login as the application user on startup.  Even without authenticating
REST clients, this would allow the gateway to work when HBase security is active.
> For step #2, we can make use of SPNEGO to provide Kerberos/GSSAPI authentication of clients
over HTTP.  The Alfredo library from Cloudera would hopefully make this relatively easy to
do:
