Markus Heiden created SOLR-7507:
-----------------------------------
Summary: Collection specific config for SolrCloud
Key: SOLR-7507
URL: https://issues.apache.org/jira/browse/SOLR-7507
Project: Solr
Issue Type: Improvement
Components: SolrCloud
Affects Versions: 5.1
Reporter: Markus Heiden
Priority: Minor
SolrCloud uses the collection abstraction and propagates to not think of cores.
But currently the collection properties are just stored as core properties of
the created cores. These won't get propagated to new nodes automatically. This
is counter-intuitive.
This patch adds the possibility to add collection specific config files. These
are put under the collection node in zookeeper. The resolution order for config
file accesses is now: 1) collection node, 2) config set node, 3) file system.
This allows for one generic config set being used for different collections
which just differ in their solrcore.properties. Furthermore the
solrcore.properties need no more to exist in the filesystem but are distributed
via zookeeper as it should be (IMO).
If you like this patch, I will add a patch for ZkCLI which allows the upload of
config files for a collection in the linkconfig command.
