I'm trying to save the PageRank data back to Neo4j, as the steps in https://neo4j.com/blog/neo4j-3-0-apache-spark-connector/ but an error occured.
My code is as follow:
import org.neo4j.spark._ import org.apache.spark.graphx._ import org.apache.spark.graphx.lib._ val neo = Neo4j(sc) val g = Neo4jGraph.loadGraph(sc, label1="node", relTypes=Seq("connect"), label2="node") val g2 = PageRank.run(g, numIter = 9) val v = g2.vertices.take(9) Neo4jGraph.saveGraph(sc, g2,"rank")
The error: org.neo4j.driver.exceptions.ClientException: Writing in read access mode not allowed. Attempted write to internal graph 0 (neo4j)
Note: everything is run well until the last line of code.
