[jira] [Updated] (SOLR-4580) Support for protecting content in ZK
[ https://issues.apache.org/jira/browse/SOLR-4580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mark Miller updated SOLR-4580:
------------------------------
Attachment: SOLR-4580.patch
Patch attached:
I've made some very small tweaks/fixes and added a new dev start scripts that runs a cloud cluster against a secured zk.
I tried to access the zk info without credentials from another zk tool with this setup - I could only see the root nodes, none of their children. I could not read the contents of the nodes. I could not delete nodes that had children (I could not see the children but got a relevant error when trying to delete nodes with children).
Oddly, it seems I could delete nodes with no children - for example cluster.json and alias.json.

> We want to protect content in zookeeper.
> In order to run a CloudSolrServer in "client-space" you will have to open for access to zookeeper from client-space.
> If you do not trust persons or systems in client-space you want to protect zookeeper against evilness from client-space - e.g.
> * Changing configuration
> * Trying to mess up system by manipulating clusterstate
> * Add a delete-collection job to be carried out by the Overseer
> * etc
> Even if you do not open for zookeeper access to someone outside your "secure zone" you might want to protect zookeeper content from being manipulated by e.g.
> * Malware that found its way into secure zone
> * Other systems also using zookeeper
> * etc.
