index all files inside a folder in solr - indexing

Question

I am having troubles indexing a folder in solr
example-data-config.xml:
<dataConfig>
<dataSource type="BinFileDataSource" />
<document>
<entity name="files"
dataSource="null"
rootEntity="false"
processor="FileListEntityProcessor"
baseDir="C:\Temp\" fileName=".*"
recursive="true"
onError="skip">
<field column="fileAbsolutePath" name="id" />
<field column="fileSize" name="size" />
<field column="fileLastModified" name="lastModified" />
<entity
name="documentImport"
processor="TikaEntityProcessor"
url="${files.fileAbsolutePath}"
format="text">
<field column="file" name="fileName"/>
<field column="Author" name="author" meta="true"/>
<field column="text" name="text"/>
</entity>
</entity>
</document>
then I create the schema.xml:
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="fileName" type="string" indexed="true" stored="true" />
<field name="author" type="string" indexed="true" stored="true" />
<field name="title" type="string" indexed="true" stored="true" />
<field name="size" type="plong" indexed="true" stored="true" />
<field name="lastModified" type="pdate" indexed="true" stored="true" />
<field name="text" type="text_general" indexed="true" stored="true" multiValued="true"/>
finally I modify the file solrConfig.xml adding the requesthandler and the dataImportHandler and dataImportHandler-extra jars:
<requestHandler name="/dataimport" class="solr.DataImportHandler">
<lst name="defaults">
<str name="config">example-data-config.xml</str>
</lst>
</requestHandler>
I run it and the result is:
Inside that folder there are like 20.000 files in diferent formats (.py,.java,.wsdl, etc)
Any suggestion will be appreciated. Thanks :)

Answer 1

Check your Solr logs . Answer for what is the Root Cause will definitely be there . I also faced same situation once and found through solr logs that my DataImportHandler was throwing exceptions because of encrypted documents present in the folder . Your reasons may be different, but first analyze your solr logs, execute your entity again in DataImport section, and then check the immediate logs for errors by going on the logging section on admin page . If you are getting errors other than I what I mentioned , post them here , so they can be understood and deciphered .
