Failed to read file while providing the avro schema for map - Map key type must be binary (UTF8): required int32 key

[jitendra sharma]

Hi All,

We have written a batch application that will read the data from s3 bucket.
File format is .snappy.parquet and that file contains the record with map
type.

Example: id : string
                id_map : map
                         key: int32
                         value: int32

I have tried to define the schema in possible ways to read the file still
Iam getting the "*Map key type must be binary (UTF8): required int32 ke*".
I gone through the Avro document it looks like the key for an Avro map must
be a string. Avro maps supports only one attribute: values. I am looking
for solution how we can read the file with map key int.

Any ideas/suggestions are appreciated.


Thank you,
