Amrit Sarkar commented on SOLR-13035:
-------------------------------------
Fresh patch uploaded, the design:
1. {{SOLR_VAR_ROOT}} introduced, defaults to {{SOLR_TIP}} (installation dir)
2. {{SOLR_DATA_HOME}} will be resolved to {{<SOLR_VAR_ROOT>}}/data if not
passed explicitly
3. {{SOLR_LOGS_DIR}} will be resolved to {{<SOLR_VAR_ROOT>}}/logs if not passed
explicitly
4. {{SOLR_PID_DIR}} will be resolved to {{<SOLR_VAR_ROOT>}}/, if not passed
then as before, {{<SOLR_TIP>}}/bin
a. SOLR_DATA_HOME now will be resolved to both instancePath and dataDir for
cores, unlike just dataDir before.
b. SOLR_DATA_HOME is not present in the server, an attempt will be made to
create the specified directory.
I have only added tests for SOLR_DATA_HOME, not sure how to test startup script
changes except manually. If everyone agrees with all good above, I will add
relevant documentation and finish this up.

> {{solr.data.home}} system property or {{solrDataHome}} in _solr.xml_ is
> already available as per SOLR-6671.
> The writable content in Solr are index files, core properties, and ZK data if
> embedded zookeeper is started in SolrCloud mode. It would be great if all
> writable content can come under the same directory to have separate READ-ONLY
> and WRITE-ONLY directories.
> It can then also solve official docker Solr image issues:
