Subject Re: EmbeddedSolrServer and Core dataDir in Solr 6.x
Date Mon, 03 Oct 2016 22:50:16 GMT
Alan,

Thanks for the response. I will double-check, but I believe that is going
to put the data directory for the core under coreHome/coreName.

What I am trying to setup (and did a poor job of explaining) is something
like the following...

- Solr home in src/test/resources/solr
- Core home in src/test/resources/myCore
- dataDir for the myCore in target/myCore (or something not in the source
tree).

This way the unit tests can use the Solr home and core config that is under
version control, but the data from testing would be written somewhere not
under version control.

in 5.x I was specifying the dataDir through the properties object... I
would calculate the path to the target dir in Java code relative to the
class file, and then pass that as dataDir to the following:

Properties props = new Properties();
props.setProperty("dataDir", dataDir + "/" + coreName);

In 6.x it seems like Properties has been replaced with the
Map<String,String> ? and I tried putting dataDir in there, but didn't seem
to do anything.

For now I have just been using RAMDirectoryFactory so that no data ever
gets written to disk.

I'll keep trying different things, but if you have any thoughts let me know.

Thanks,

Bryan
