我有以下 PySpark 数据框：
StructType([
StructField('data', ArrayType(StructType([
StructField('awayPlayers', ArrayType(StructType([
StructField('number', StringType(), True),
StructField('optaId', StringType(), True),
StructField('playerId', StringType(), True),
StructField('speed', DoubleType(), True),
StructField('xyz', ArrayType(DoubleType(), True), True)
]), True), True),
StructField('ball', StructType([
StructField('speed', DoubleType(), True),
StructField('xyz', ArrayType(DoubleType(), True), True)
]), True),
StructField('frameIdx', LongType(), True),
StructField('gameClock', StringType(), True),
StructField('homePlayers', ArrayType(StructType([
StructField('number', StringType(), True),
StructField('optaId', StringType(), True),
StructField('playerId', StringType(), True),
StructField('speed', DoubleType(), True),
StructField('xyz', ArrayType(DoubleType(), True), True)
]), True), True),
StructField('period', LongType(), True),
StructField('wallClock', LongType(), True)
]), True), True),
StructField('feedName', StringType(), True),
StructField('gameId', StringType(), True),
StructField('league', StringType(), True),
StructField('messageId', StringType(), True)
])
我从 JSON 文件中读入。我想将其展平，其中 homePlayers 和awayPlayers 位于单独的行上。
我尝试过以下方法：
# Flatten the DataFrame
flattened_df = df.selectExpr("league", "gameId", "feedName", "messageId", "data.*")
flattened_df = flattened_df.select("league", "gameId", "feedName", "messageId", explode("data.awayPlayers").alias("awayPlayers"), "data.ball", "data.frameIdx", "data.gameClock", explode("data.homePlayers").alias("homePlayers"))
但我收到以下错误：
AnalysisException: Can only star expand struct data types. Attribute: `ArrayBuffer(data)`; line 1 pos 0

请帮忙
正如另一个答案已经说过的那样，您遇到的问题是因为您试图以只能
selectselect首先，您需要
explodeexplodeawayPlayershomePlayers对于你的情况，你可以这样做：
from pyspark.sql.functions import explode, col
df = spark.read.json("./bigJson.json")
flattened_df = df \
.select("league", "gameId", "feedName", "messageId", explode("data").alias("data")) \
.select("league", "gameId", "feedName", "messageId", col("data.awayPlayers").alias("awayPlayers"), "data.ball", "data.frameIdx", "data.gameClock", col("data.homePlayers").alias("homePlayers")) \
.withColumn("awayPlayers", explode("awayPlayers")) \
.withColumn("homePlayers", explode("homePlayers"))
flattened_df.printSchema()
root
|-- league: string (nullable = true)
|-- gameId: string (nullable = true)
|-- feedName: string (nullable = true)
|-- messageId: string (nullable = true)
|-- awayPlayers: struct (nullable = true)

| |-- xyz: array (nullable = true)
| | |-- element: double (containsNull = true)
|-- frameIdx: long (nullable = true)
|-- gameClock: string (nullable = true)
|-- homePlayers: struct (nullable = true)
| |-- number: string (nullable = true)

| |-- playerId: string (nullable = true)
| |-- speed: double (nullable = true)

| | |-- element: double (containsNull = true)
您收到的错误来自您选择中的
data.*您的原始行包含一个
dataawayPlayershomePlayers您使用
