Shalin Shekhar Mangar commented on SOLR-13035:
----------------------------------------------
Why should there be a "var" directory under the unzipped solr? "var" doesn't
mean anything on windows, for example. Most datastores ship with a logs and
data directory right under the unzipped root. I think we should do the same and
not introduce new environment variables. Also, it should be possible to point
data and logs to separate mount points which a new SOLR_VAR_ROOT doesn't hinder
but doesn't help with too.
If someone wants to move all such writable directories under one then they can
set multiple variables (which already exist and are relatively well known) or
they can mount to multiple places. This will likely be done by the docker-solr
project so it is not like everyone has to make this decision. I'd be okay going
with your proposal if getting rid of the myriad of properties we already have
is part of the plan but if not, then adding one more just causes more confusion
I feel.

> {{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:
