Hi guys,

I'm having some issues when trying to use the DataImportHandler on Solr
4.0.
I've downloaded the latest nightly build of Solr 4.0 and configured normally
(on the example folder) solrconfig.xml file like this:

<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>

At this point I noticed that the DIH jar was not being loaded correctly
causing exceptions like:
Error loading class 'org.apache.solr.handler.dataimport.DataImportHandler'
and
java.lang.ClassNotFoundException:
org.apache.solr.handler.dataimport.DataImportHandler

Do I need to build to get DIH running on Solr 4.0?

Thanks!
Alexandre

The DIH is no longer supplied embedded in the Solr war file.  You need to get it on the classpath somehow. You could add another <lib... statement to solrconfig.xml to resolve this.

Curious...why was this feature removed?

It is a contrib module. But the example solrconfig should have the lib set.

: Curious...why was this feature removed?

it hasn't been removed, it still ships with the solr releases as a contrib
jar the same way it always did.

what changed is that in the past it was mistakenly/foolishly/inexplicable
also included in the solr.war -- even though it didn't need to be.

This is loudly noted in the upgrading section of CHANGES.txt so people who
were using it in previous releases and expected to it be embeded in the
solr.war will have notice that they should update their configuration to
include it as a plugin...

https://svn.apache.org/viewvc/lucene/dev/branches/branch_3x/solr/CHANGES.txt?r1=1071480&r2=1072131

...for people starting with the 3.x or 4.x example-DIH config files, they
already include the neccessary <lib/> declaration.

I got it working by building the DIH from the contrib folder and made a
change on the lib statements to map the folder that contains the .jar files.

Thanks!

It seems this thread has been hijacked. My initial posting was in
regards to my custom Evaluators always receiving a null context. Same
Evaluators work in 1.4.1

I'm pretty sure you are talking about a completely different thread, with
a completely differnet subject ("Solr 4.0 DIH")

-Hoss

Not a java pro, and the documentation hasn't been updated to include these
instructions (at least that I could find). What do I need to do to perform
the steps that Alexandre is talking about?

You need to find "apache-solr-solrj-4.0.jar" from your distribution and put it in the classpath somewhere.  Perhaps the easiest thing is to include it in your core's "lib" directory.
