Read JSON files from multiple line file in spark scala

Question

I'm learning spark in Scala. I have a JSON file as follows:

[
  {
    "name": "ali",
    "age": "13",
    "phone": "09123455737",
    "sex": "m"
  },{
    "name": "amir",
    "age": "24",
    "phone": "09123475737",
    "sex": "m"
  }
]

and there is just this code:

val sqlContext = new org.apache.spark.sql.SQLContext(sc)
val jsonFile = sqlContext.read.json("path-to-json-file")

I just receive corrupted_row : String nothing else but when put every person(or objects) in single row, code works fine

How can I read from multiple lines for a JSON sqlContext in spark?

Answer 1

您必须自己将其读入 RDD，然后将其转换为数据集：

spark.read.json(sparkContext.wholeTextFiles(...).values)          

Answer 2

This problem is getting caused because you have multiline json row. Although by default spark.read.json expect a row to be in a single line but this is configurable:

You can set option spark.read.json("path-to-json-file").option("multiLine", true)
