Wrong escape character in avro.schema.url

When doing the export from hive to S3 it creates the following:
```
WITH SERDEPROPERTIES (
  'avro.schema.url'='s3\\://bucket/directory/_schema.avsc')
```
and this cannot be parsed correctly
Is it possible to fix to avoid that? Because when I replace with:
```
WITH SERDEPROPERTIES (
  'avro.schema.url'='s3://bucket/directory/_schema.avsc')
```
it works as expected
