Distributed group query, if rename the unique key field name, will be java.lang.NullPointerException.

[Dawn <li...@live.com>]

Hi:
	Distributed group query, if rename the unique key field name, will be java.lang.NullPointerException.

	Because of without StoredFieldsShardResponseProcessor processing rename.

	Can I create an issue to fix it?


query("q", "*:*", "rows", 100, "fl", “aliasName:id," + i1, "group", "true", "group.field", i1, "group.limit", -1, "sort", i1 + " asc, id asc");
