Review request for hbase, Gary Helmling and Eugene Koontz.
Changes
-------
Unconditionally pull in ZK 3.4.
Some of the POM changes might reject, depending on what goes in first, but
would be trivial to fix up.
Summary
-------
These changes add support for protecting the state of HBase znodes on a
multi-tenant ZooKeeper cluster. This support requires ZK 3.4.0, currently at
RC2. It is a companion patch to HBASE-2742 (secure RPC), and HBASE-3025
(Coprocessor based access control).
SASL authentication of ZooKeeper clients with the quorum is handled in the ZK
client independently of HBase concerns. To enable strong ZK authentication, one
must create a suitable JaaS configuration, for example:
Server {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
keyTab="/etc/hbase/conf/hbase.keytab"
storeKey=true
useTicketCache=false
principal="zookeeper/$HOSTNAME";
};
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
useTicketCache=false
keyTab="/etc/hbase/conf/hbase.keytab"
principal="hbase/$HOSTNAME";
};
and then configure both the client and server processes to use it, for example
in hbase-site.xml:
HBASE_OPTS="${HBASE_OPTS}
-Djava.security.auth.login.config=/etc/hbase/conf/jaas.conf"
HBASE_OPTS="${HBASE_OPTS} -Dzookeeper.kerberos.removeHostFromPrincipal=true"
HBASE_OPTS="${HBASE_OPTS} -Dzookeeper.kerberos.removeRealmFromPrincipal=true"
HBase will then secure all znodes but for a few world-readable read-only ones
needed for clients to look up region locations. All internal cluster operations
will be protected from unauthenticated ZK clients, or clients not authenticated
to the HBase principal. Presumably the only ZK clients authenticated to the
HBase principal will be those embedded in the master and regionservers.
There is extraneous whitespace in code surrounding these changes.
This addresses bug HBASE-2418.

Testing
-------
These changes are running in production at Trend Micro, using a snapshot build
of ZooKeeper 3.4.0.
New unit test TestZooKeeperACL passes 100 iterations. All test pass not
otherwise currently failing on trunk.

> Project: HBase
> Issue Type: Improvement

> Priority: Critical
> Labels: security, zookeeper
> Fix For: 0.92.0
>
>
> Some users may run a ZooKeeper cluster in "multi tenant mode" meaning that
> more than one client service would
> like to share a single ZooKeeper service instance (cluster). In this case the
> client services typically want to protect
> their data (ZK znodes) from access by other services (tenants) on the
> cluster. Say you are running HBase and Solr
> and Neo4j, or multiple HBase instances, etc... having
> authentication/authorization on the znodes is important for both
> security and helping to ensure that services don't interact negatively (touch
> each other's data).
> Today HBase does not have support for authentication or authorization. This
> should be added to the HBase clients
> that are accessing the ZK cluster. In general it means calling addAuthInfo
> once after a session is established:
> http://hadoop.apache.org/zookeeper/docs/current/api/org/apache/zookeeper/ZooKeeper.html#addAuthInfo(java.lang.String,
> byte[])
> with a user specific credential, often times this is a shared secret or
> certificate. You may be able to statically configure this
> in some cases (config string or file to read from), however in my case in
> particular you may need to access it programmatically,
> which adds complexity as the end user may need to load code into HBase for
> accessing the credential.
> Secondly you need to specify a non "world" ACL when interacting with znodes
> (create primarily):
> http://hadoop.apache.org/zookeeper/docs/current/api/org/apache/zookeeper/data/ACL.html
> http://hadoop.apache.org/zookeeper/docs/current/api/org/apache/zookeeper/ZooDefs.html
> Feel free to ping the ZooKeeper team if you have questions. It might also be
> good to discuss with some
> potential end users - in particular regarding how the end user can specify
> the credential.
