Re: [Neo4j] BatchInserter - No index provider 'null' error
Ah, it's a bug allright... only when using the BatchInserterIndex. The
problem goes away if you add provider:lucene to the configuration map,
like:
persons= indexProvider.nodeIndex(persons,
MapUtil.stringMap(type,exact,
provider, lucene));
It will be fixed in M03, where the LuceneBatchInserterIndexProvider fills
that in for you.

Paddy,
just tested it, and it seems it only occurs when running standalone,
see the other mail. Seems to be a bug, and I think it is linked to the
behavior seen in the Python bindings, too.

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

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
