Compressor detection can only be called on some ……

今天写的ES客户端测试的文件里一个方法报错，方法体如下：

public IndexResponse createIndex(String indexName, String type,
			String jsonArray) {

		IndexRequestBuilder builder = client.prepareIndex(indexName, type).setSource(jsonArray);
		
		IndexResponse response = builder.execute().actionGet();
		return response;

	}

报错内容如下：

在我这里造成这一异常  的原因是传递的参数jsonArray格式不对，我打印了下jsonArray，格式如下：

[{"name":"hui1","salary":10000.39982635574,"age":8},
{"name":"hui2","salary":10000.160206564933,"age":11},
{"name":"hui3","salary":10000.417013742277,"age":28},
{"name":"hui4","salary":10000.26786620842,"age":7}]

这里正确的格式应该是这样：

{"name":"hui1","salary":10000.39982635574,"age":8}

即便将原来以 "[" 开关的jsonArray去年“[”,改成这样：

{"name":"hui1","salary":10000.39982635574,"age":8},
{"name":"hui2","salary":10000.160206564933,"age":11},
{"name":"hui3","salary":10000.417013742277,"age":28},
{"name":"hui4","salary":10000.26786620842,"age":7}

也一样会报错。
