Possible Bug: Bulk operation doesn't use defaultType value

[pulkitsinghal]

I setup my code like so:

Builder bulkIndexBuilder = new Bulk.Builder()
        .defaultIndex("my_index_name")
        .defaultType("my_index_type");
...
for (...) {
    Index index = new Index.Builder(source)
                            .id(id)
                            .build();
    bulkIndexBuilder = bulkIndexBuilder.addAction(index);
}
...
Bulk bulk = bulkIndexBuilder.build();
client.execute(bulk);

But what I get back is something like:

"items": [
    {
        "index": {
            "_index": "my_index_name", 
            "_type": "_all", 
            "_id": "...", 
            "error": "InvalidTypeNameException[mapping type name [_all] can't start with '_']"
        }
    },
...
]

Which means the defaultType value of my_index_type that I had setup wasn't used!
Looks like a bug to me ... am I mistaken?

You are right this is a bug, AbstractDocumentTargetedAction.Builder was too smart for its own good and set the type parameter to "_all" by default and this caused defaultType to be ineffective.
