pysparkで下記のようなエラーが発生しています．
stringJSONRDD = sc.parallelize(("""
{ "id": "123",
"name": "Katie",
"age": 19,
"eyeColor": "brown"
}""",
"""{
"id": "234",
"name": "Michael",
"age": 22,
"eyeColor": "green"
}""",
"""{
"id": "345",
"name": "Simone",
"age": 23,
"eyeColor": "blue"
}""")
)
を行い，RDDを定義した後
swimmersJSON = spark.read.json(stringJSONRDD)
でDataFrameに変換した後．
spark.sql("select*from swimmersJSON").collect()
を実行すると

といったエラーが出ます．どうすればよろしいでしょうか？
なお
spark.sql("show databases").show
では
<bound method DataFrame.show of DataFrame[databaseName: string]>
と処理はされている様子です．
./build/mvn -DskipTests clean package
のテストや
./python/run-testは全部通っています．
