Jan Høydahl updated SOLR-6671:
------------------------------
Attachment: SOLR-6671.patch
New patch
* Test of the getDataHome() method
* Uses last path element of instanceDir instead of coreName.
I'm not 100% sure of the last change, using last path element of instanceDir
instead of core name. These will be equal if instanceDir is not overridden, but
if changed, the burden will be on the user to choose instanceDir with
non-overlapping last path components.
> Introduce a solr.data.home as root dir for all data

> Many users prefer to deploy code, config and data on separate disk locations,
> so the default of placing the indexes under
> {{$\{solr.solr.home\}/$\{solr.core.name\}/data}} is not always wanted.
> In a multi-core/collection system, there is not much help in the
> {{solr.data.dir}} option, as it would set the {{dataDir}} to the same folder
> for all collections. One workaround, if you don't want to hardcode paths in
> your {{solrconfig.xml}}, is to specify the {{dataDir}} property in each
> {{solr.properties}} file.
> A more elegant solution would be to introduce a new Java-option
> {{solr.data.home}} which would be to data the same as {{solr.solr.home}} is
> for config. If set, all collections would default their {{dataDir}} as
> {{$\{solr.data.home\)/$\{solr.core.name\}/data}}
