Hello,
I'm exploring SparkSQL and I'm facing issue while using the queries. Any
help on this is appreciated.
I have the following schema once loaded as RDD.
root
|-- data: array (nullable = true)
| |-- element: struct (containsNull = false)
| | |-- age: integer (nullable = true)
| | |-- name: string (nullable = true)
my people.json is as follows.
{"data": [{"name":"Michael"}, {"name":"Andy", "age":30}, {"name":"Justin",
"age":19}]}
when I'm querying "select name from people where age>=13"; I'm getting the
following exception.
org.apache.spark.sql.catalyst.errors.package$TreeNodeException: Unresolved
attributes: 'element.name, tree:
Project ['name]
Filter ('age >= 13)
Subquery people
My question is how to access name, age from root node to query the same.
Thanks in advance.
