Implement a SOLR specific naming service (using Zookeeper)
----------------------------------------------------------
Key: SOLR-1277
URL: https://issues.apache.org/jira/browse/SOLR-1277
Project: Solr
Issue Type: New Feature
Affects Versions: 1.4
Reporter: Jason Rutherglen
Priority: Minor
Fix For: 1.5
The goal is to give SOLR server clusters self-healing attributes
where if a server fails, indexing and searching don't stop and
all of the partitions remain searchable. For configuration, the
ability to centrally deploy a new configuration without servers
going offline.
We can start with basic failover and start from there?
Features:
* Automatic failover (i.e. when a server fails, clients stop
trying to index to or search it)
* Centralized configuration management (i.e. new solrconfig.xml
or schema.xml propagates to a live SOLR cluster)
* Optionally allow shards of a partition to be moved to another
server (i.e. if a server gets hot, move the hot segments out to
cooler servers). Ideally we'd have a way to detect hot segments
and move them seamlessly. With NRT this becomes somewhat more
difficult but not impossible?
