How to use pyspark in pycharm to connect to the graph database and call the graph algorithm？

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'?

Solution

  • try in this way:

    from pyspark.sql import DataFrame

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