java - Apache Solr DataImportHandler failes trying to index -

-

i trying index xml files solr 6.2.1 using dataimporthandler.

for purpose have added needed import , requesthandler solrconfig.xml:

  <lib dir="${solr.install.dir:../../../..}/contrib/dataimporthandler/lib/" regex=".*\.jar" />   <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />    <requesthandler name="/dataimport" class="org.apache.solr.handler.dataimport.dataimporthandler" startup="lazy">     <lst name="default">         <str name="config">data-config.xml</str>     </lst>   </requesthandler>

then wrote data-config.xml , put same path solrconfig.xml:

<dataconfig>     <datasource type="filedatasource" encoding="utf-8"/>     <document>         <entity name="pickupdir"                 processor="filelistentityprocessor"                 datasource="null"                 basedir="/vagrant/trec8all/adhoc/"                 recursive="true"                 filename="^[\w\d-]+\.xml$" />         <entity name="trec8_simple"                 processor="xpathentityprocessor"                 stream="true"                 datasource="pickupdir"                 url="${pickupdir.fileabsolutepath}"                 foreach="/docs/doc">             <field column="id" xpath="/docs/doc/docno"/>             <field column="header" xpath="/docs/doc/header"/>             <field column="text" xpath="/docs/doc/text"/>         </entity>     </document> </dataconfig>

this should make importhandler iterate recursively through xml files in directory , index them according xpaths.

when call requesthandler this: (i running solr in vagrant box instead of locally)

http://192.168.155.156:8983/solr/trec8/dataimport?command=full-import&entity=trec8_simple

i getting exception in solr.log:

error (thread-14) [   x:trec8] o.a.s.h.d.dataimporter full import failed:java.lang.nullpointerexception         @ org.apache.solr.handler.dataimport.dataimporter.createpropertywriter(dataimporter.java:325)         @ org.apache.solr.handler.dataimport.dataimporter.dofullimport(dataimporter.java:412)         @ org.apache.solr.handler.dataimport.dataimporter.runcmd(dataimporter.java:475)         @ org.apache.solr.handler.dataimport.dataimporter.lambda$runasync$0(dataimporter.java:458)         @ java.lang.thread.run(thread.java:745)

im assuming should source dataimporthandler:

https://github.com/sudarshang/lucene-solr/blob/master/solr/contrib/dataimporthandler/src/java/org/apache/solr/handler/dataimport/dataimporter.java

i have trouble figuring out causing exception , meaning. nice if me out. thanks!

edit: think has dataimporthandler not beeing able finde data-config.xml. when remove throw exact same exception

ok found issue! problem in solrconfig,

<lst name="default">     <str name="config">data-config.xml</str> </lst>

should have been

<lst name="defaults">     <str name="config">data-config.xml</str> </lst>
