The configuration for the data directory in Solr is typically found in the solrconfig.xml file. This file is located in the conf directory of each Solr core or collection.

In the provided XML files, the data directory is configured with the <dataDir> tag. The value of this tag is set to ${solr.data.dir:}, which means it will use the value of the solr.data.dir system property if it is set, otherwise, it will default to an empty string.

Here are the relevant sections from the provided XML files:

File 1: solr/core/src/test-files/solr/collection1/conf/solrconfig-implicitproperties.xml

<config>
  ...
  <dataDir>${solr.data.dir:}</dataDir>
  ...
</config>

File 2: solr/solrj-streaming/src/test-files/solrj/solr/configsets/ml/conf/solrconfig.xml

<config>
  ...
  <dataDir>${solr.data.dir:}</dataDir>
  ...
</config>

If you need to change the data directory, you can do so by setting the solr.data.dir system property to the desired path. This can be done when starting Solr by adding -Dsolr.data.dir=/path/to/data/dir to the command line. Alternatively, you can directly modify the <dataDir> tag in the solrconfig.xml file to point to the desired directory, but this is not recommended as it can lead to inconsistencies if the system property is also set.
