I'm currently using **Elasticsearch's** `_bulk` API to import a JSON dump.  
There is a field that has a dynamic data type, i.e. a `Boolean` type and an `Object` type.

Due to this, while importing the dump, elasticsearch throws an exception saying

```
{ type: 'illegal_argument_exception',
  reason: 'mapper **myfieldName** of different type, current_type [boolean], merged_type [ObjectMapper]' }

```

How can I handle this scenario?

I don't think you can. It can't be both an object and a native field.
