Andrew Purtell commented on HBASE-2418:
---------------------------------------
bq. 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
So this is some config on the HBase side involving reflection and HBase users
would need to deploy some jar onto the HBase classpath, I assume.
> add support for ZooKeeper authentication

> Key: HBASE-2418
> URL: https://issues.apache.org/jira/browse/HBASE-2418
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: master, regionserver
> Reporter: Patrick Hunt
> Priority: Critical
>
> 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.
