Hi,
I'm trying out the new Index Framework Batch Inserter using version 1.2.M02.
I getting a "No index provider 'null' found" error when calling
graphDb.index().forNodes("persons") in my test code below
Exception in thread "main" java.lang.IllegalArgumentException: No index
provider 'null' found
at
org.neo4j.kernel.IndexManagerImpl.getIndexProvider(IndexManagerImpl.java:65)
at org.neo4j.kernel.IndexManagerImpl.forNodes(IndexManagerImpl.java:205)
at
ie.transportdublin.batchinserter.BatchIndexTest.main(BatchIndexTest.java:40)
>From debugging it looks like config.get( KEY_INDEX_PROVIDER )@ L205 in
IndexManagerImpl
is returning a null value.
Or please let me know if I should be doing this a different way.
thanks
Paddy
