Neptune 載入器 Get-Status errorLogs 範例

發生錯誤時的詳細狀態回應範例

這是通過HTTPGET使用以curl下方式發送的請求

curl -X GET 'https://your-neptune-endpoint:port/loader/0a237328-afd5-4574-a0bc-c29ce5f54802?details=true&errors=true&page=1&errorsPerPage=3'

範例 發生錯誤時的詳細回應

這是您可能從上面查詢中取得的回應範例，其中 errorLogs 物件列出了遇到的載入錯誤：

{
    "status" : "200 OK",
    "payload" : {
        "failedFeeds" : [
            {
                "datatypeMismatchErrors" : 0,
                "fullUri" : "s3://bucket/key",
                "insertErrors" : 0,
                "parsingErrors" : 5,

                "totalRecords" : 5,
                "totalTimeSpent" : 3.0
            }
        ],
        "feedCount" : [
            {
                "LOAD_FAILED" : 1
            }
        ],

        },
        "errors" : {
            "endIndex" : 3,
            "errorLogs" : [
                {
                    "errorCode" : "PARSING_ERROR",
                    "errorMessage" : "Expected '<', found: |",
                    "fileName" : "s3://bucket/key",
                    "recordNum" : 1
                },
                {
                    "errorCode" : "PARSING_ERROR",
                    "errorMessage" : "Expected '<', found: |",
                    "fileName" : "s3://bucket/key",
                    "recordNum" : 2
                },
                {
                    "errorCode" : "PARSING_ERROR",
                    "errorMessage" : "Expected '<', found: |",
                    "fileName" : "s3://bucket/key",
                    "recordNum" : 3
                }
            ],
            "loadId" : "0a237328-afd5-4574-a0bc-c29ce5f54802",
            "startIndex" : 1
        }
    }
}

Data prefetch task interrupted 錯誤的範例

有時候當您取得 LOAD_FAILED 狀態並接著請求更多詳細資訊時，這時傳回的錯誤可能為 PARSING_ERROR 並搭配 Data prefetch task interrupted 訊息，如下所示：

"errorLogs" : [
    {
        "errorCode" : "PARSING_ERROR",
        "errorMessage" : "Data prefetch task interrupted: Data prefetch task for 11467 failed",
        "fileName" : "s3://some-source-bucket/some-source-file",
        "recordNum" : 0
    }
]

當資料載入作業發生通常原因不在於您的請求或資料的暫時中斷時，就會出現這個錯誤。通常只要再次執行大量上傳請求，就能解決這個問題。如果您使用的是預設設定，即 "mode":"AUTO" 和 "failOnError":"TRUE"，這時載入器會略過其已成功載入的檔案，並恢復其在中斷發生時尚未載入的檔案載入。
