Neo4j Import tool error in RC01

Question

I've successfully imported a large Neo4j database on 2.2M03 using the batch import tool. But now I need to use 2.2RC01 and cannot use the same import tool where I get a Import null error when I use the identical files I've used for the previous import.

The message.log reads:

2015-03-14 08:36:19.670+0000 INFO  [org.neo4j]: Import starting

Something weird is that at one point, the import failed after importing n number of nodes and the other after importing a different number of nodes.

Is there a change in the format of files in 2.2RC01? I've read the manual but didn't spot any difference.

Can you share your files with us? You can also email me via michael at neo4j.org — Michael Hunger
