I do something similar, but without the placeholders in db-data-config.xml. You
can define the entire datasource in solrconfig.xml, then leave out that element
entirely in db-data-config.xml. It seems really odd, but that is how the code
works.
This is working for me in 4.1, so it might be a workaround for you.
It looks like this:
<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">db-data-config.xml</str>
<lst name="datasource">
<str name="defType">JdbcDataSource</str>
<str name="driver">com.mysql.jdbc.Driver</str>
<str name="url">jdbc:mysql://${textbooks.dbhost:nohost}/xxxx</str>
<str name="user">${textbooks.dbuser:yyyyy}</str>
<str name="password">${textbooks.dbpass:zzzzzz}</str>
<str name="batchSize">-1</str>
<str name="readOnly">true</str>
<str name="onError">skip</str>
<str name="netTimeoutForStreamingResults">600</str>
<str name="zeroDateTimeBehavior">convertToNull</str>
</lst>
</lst>
</requestHandler>
