Question

How to use pyspark in pycharm to connect to the graph database and call the graph algorithm? Is there such api?

Also,may I ask how the object class 'py4j.java_gateway.JavaObject' after calling the graph algorithm is converted back to the pyspark dataframe object class 'pyspark.sql.dataframe.DataFrame'?

Answer 1

try in this way:

from pyspark.sql import DataFrame

jdf = jdf.toDF()
df = DataFrame(jdf, spark)
