elasticsearch入庫錯誤 mapper_parsing_exception

    最近在使用java api進行ES入庫操做時，報以下錯誤：

{"took":150,"errors":true,"items":[{"index":{"_index":"test","_type":"type1","_id":"794719072","status":400,"error":{"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"not_x_content_exception","reason":"Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"}}}}

通過排查發現，在入庫過程當中，java錯誤的將字符串1 （「1」）進行了入庫操做，即將以下格式的數據進行入庫：

{"index":{"_index":"test","_type":"type1"}}
"1"

 則會報上述錯誤，入庫數據格式有誤，mapping沒法解析
