Subject [jira] [Commented] (SOLR-13035) Utilize solr.data.home / solrDataHome in solr.xml to set all writable files in single directory
Date Fri, 14 Dec 2018 20:20:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-13035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16721757#comment-16721757

Jan Høydahl commented on SOLR-13035:
------------------------------------

What exactly is SOLR_TIP here? After a default Linux install script install, SOLR_TIP is
{{/opt/solr}} if I'm not mistaken, which would typically be R/O.

Perhaps what we'd need is a new env.var {{SOLR_VAR_ROOT}} that would be the root of all writable
files, then {{-t data -l logs}} would translate into {{SOLR_VAR_ROOT/data}} and {{SOLR_VAR_ROOT/logs}},
and installers could simply install Solr to somewhere (e.g. C:\ProgramFiles\Solr) and set
e.g. {{SOLR_VAR_ROOT=D:\}} and the defaults would then be for SOLR_HOME, SOLR_DATA_DIR, SOLR_LOGS_DIR
and SOLR_PID_DIR to be relative to that.

> {{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:
