[jira] [Commented] (SOLR-5916) DIH datasource init borks if url attribute contains two property references

["Gunnlaugur Thor Briem (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-5916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13949074#comment-13949074 ] 

Gunnlaugur Thor Briem commented on SOLR-5916:
---------------------------------------------

Note: the latter config is not a valid hint as to what the problem is; it only works because the first property reference resolves to the empty string and postgresql:///corename works on my test machine (PG runs on the same machine). The defaulting syntax {{$\{dbhost:foo.datamarket.net\}}} is not supported, I guess.

> With a datasource set up like this:

> user="solr"
> password="${dbpassword}"

> autoCommit="false"
> transactionIsolation="TRANSACTION_READ_COMMITTED" holdability="CLOSE_CURSORS_AT_COMMIT"
> />
> {code}
> (where dbhost and dbpassword are set in solrcore.properties)
> ... the datasource initialization (and thus any import) fails with:
> {code}

> and now it runs without problems.
> So presumably there's a bug in parsing property references.
