For example, if JSON file that includes not listed by JSON backslash
quoting specification, it returns corrupt_record
JSON File
{"name": "Cazen Lee", "price": "$10"}
{"name": "John Doe", "price": "\$20"}
{"name": "Tracy", "price": "$10"}
corrupt_record(returns null)
scala> df.show
+--------------------+---------+-----+
| _corrupt_record| name|price|
+--------------------+---------+-----+
| null|Cazen Lee| $10|
|{"name": "John Do...| null| null|
| null| Tracy| $10|
+--------------------+---------+-----+
And after apply this patch, we can enable
allowBackslashEscapingAnyCharacter option like below
scala> val df =
sqlContext.read.option("allowBackslashEscapingAnyCharacter",
"true").json("/user/Cazen/test/test2.txt")
df: org.apache.spark.sql.DataFrame = [name: string, price: string]
scala> df.show
+---------+-----+
| name|price|
+---------+-----+
|Cazen Lee| $10|
| John Doe| $20|
| Tracy| $10|
+---------+-----+
