Hi I've recently installed the community version of Neo4j on my 32 bit(Windows7) machine. I'm trying to use the Neo4jImport tool to upload csv data but have been unsuccessful. Below are the details of the data and the script:
Data (stored at C:\Neo4j\AUData): "AUCustHeader.csv" has just one row as below customerId:ID,:LABEL "AUCust.csv" has ~150k rows in the below format (no header) 100539589,Customer 111738174,Customer 115191760,Customer 117774313,Customer 119793144,Customer "AUTxnsHeader.csv" has just one row as below START_ID,Txns,:END_ID,:TYPE "AUTxns.csv" has ~98k rows in the below format (no header) 100539589,1,7000000000587269043,SENT_TO 100539589,1,7000000000621301017,SENT_TO 111738174,2,7000000000565458678,SENT_TO 115191760,1,7000000000341672243,SENT_TO 115191760,1,7000000000399157660,SENT_TO Below is script I'm executing on the powershell: PS C:\neo4j\bin> C:\Neo4j\bin\Neo4jImport --into C:\Neo4j\AUData\AU.db --nodes:Cust C:\Neo4j\AUData\AUCustHeader.csv, C:\Neo4j\AUData\AUCust.csv --relationships: SENT_TO C:\Neo4j\AUData\AUTxnsHeader.csv, C:\Neo4j\AUData\AUTxns.csv Running this gives me the below message: WARNING!
