Subject [jira] [Commented] (SOLR-4580) Support for protecting content in ZK
Date Tue, 02 Sep 2014 21:09:22 GMT


Shalin Shekhar Mangar commented on SOLR-4580:

This has broken the start scripts as well as the cloud-dev scripts. On starting solr using
./bin/solr -c, I see the following in the logs:

2204 [main] ERROR org.apache.solr.servlet.SolrDispatchFilter  – Could not start Solr. Check
solr/home property and the logs
2224 [main] ERROR org.apache.solr.core.SolrCore  – null:java.lang.StringIndexOutOfBoundsException:

> 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.
