sc = SparkSession.builder.getOrCreate()
v = sc.createDataFrame([("a",), ("b",), ], ["id", ])
e = sc.createDataFrame([("a", "b"), ], ["src", "dst"])
g = GraphFrame(v, e)
g.inDegrees.show()Warnings:
pyspark/sql/dataframe.py:148: UserWarning: DataFrame.sql_ctx is an internal property, and will be removed in future releases. Use DataFrame.sparkSession instead.
which is raised by g = GraphFrame(v, e) at
