Subject [jira] [Commented] (HBASE-2418) add support for ZooKeeper authentication
Date Mon, 21 Nov 2011 00:41:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13153923#comment-13153923
] 

Andrew Purtell commented on HBASE-2418:
---------------------------------------

And it looks like this part of the POM in trunk is not in the POM on 0.92:

{code}
  <pluginRepositories>
    <pluginRepository>
      <id>ghelmling.testing</id>
      <name>Gary Helmling test repo</name>
      <url>http://people.apache.org/~garyh/mvn/</url>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
      <releases>
        <enabled>true</enabled>
      </releases>
    </pluginRepository>
  </pluginRepositories>
{code}

I don't know enough about Maven or how Gary set up the security profile to know if it is needed
or not. Gary?

> 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.
