使用dataimporthandler solr导入csv

Question

I am trying to use solr with DIH to index csv files. I've patched my DIH library using patch SOLR-2549 mentioned on the solr wiki (see http://wiki.apache.org/solr/DataImportHandler#Configuration_in_data-config.xml-1 ) in order to import csv files without using Transformers along with LineEntityProcessor.

Unfortunately, I could not get my import work and I have the following error stack:

INFO: [csv] webapp=/solr path=/dataimport params={command=full-import&optimize=false&clean=true&commit=true&verbose=true} status=0 QTime=33 {deleteByQuery=*:*} 0 33

I think it's related to my data configuration. This is my data-config.xml file:

<dataConfig>
    <dataSource name="dfs" type="FileDataSource"/>
    <document>
        <entity name="sourcefile"
                processor="FileListEntityProcessor"
                fileName="rocinter.csv"
                rootEntity="false"
                baseDir="/user/xxx/work/solr/example/example-DIH/solr/csv/inputfolder"
        >

            <entity name="entryline"
                    processor="LineEntityProcessor"
                    url="${sourcefile.fileAbsolutePath}"
                    rootEntity="true"
                    dataSource="fds"
                    separator=","
            >
            </entity>
        </entity>
    </document>
</dataConfig>

Could anybody help me undestand this issue or provide a clear config file using patched LineEntityProcessor version to import csv files ?

I'v finally got an answer from the user mailing list. Actually that was a bug in the patch.

A newer version of the patch is attached to jira issue.
