odps平臺將資料匯入到hdfs

根據指導文件，我寫了一個指令碼，如下：
{

"order":{
    "hops":[
        {
            "from":"Reader",
            "to":"Writer"
        }
    ]
},
"setting":{
    "errorLimit":{
        "record":"1000000"
    },
    "speed":{
        "concurrent":1,
        "dmu":1,
        "throttle":false
    }
},
"steps":[
    {
        "category":"reader",
        "name":"Reader",
        "parameter":{
            "column":[
                "*"
            ],
            "datasource":"BigDataEast",
            "partition":["datatype='ali'"],
            "table":"dwd_user_map"
        },
        "stepType":"odps"
    },
    {
        "category":"writer",
        "name":"Writer",
        "parameter":{
            "column":[
                {
                    "name":"col1",
                    "type":"string"
                },
                {
                    "name":"col2",
                    "type":"string"
                },
                {
                    "name":"col3",
                    "type":"string"
                },
                {
                    "name":"col4",
                    "type":"string"
                },
                {
                    "name":"col5",
                    "type":"string"
                },
                {
                    "name":"col6",
                    "type":"string"
                },
                {
                    "name":"col7",
                    "type":"string"
                },
                {
                    "name":"col8",
                    "type":"string"
                },
                {
                    "name":"col9",
                    "type":"string"
                },
                {
                    "name":"col10",
                    "type":"string"
                },
                {
                    "name":"col11",
                    "type":"string"
                },
                {
                    "name":"col12",
                    "type":"string"
                },
                {
                    "name":"col13",
                    "type":"string"
                }
            ],
            "compress":"gzip",
            "datasource":"hadoop_test",
            "encoding":"UTF-8",
            "fieldDelimiter":"\n",
            "fileName":"test1",
            "fileType":"text",
            "path":"/cdm",
            "writeMode":"append"
        },
        "stepType":"hdfs"
    }
],
"type":"job",
"version":"2.0"

}

但是執行時候報了一個很莫名其妙的錯誤
Caused by: org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /szb_data__873b21de_085c_44cd_954a_fbaf386cec38/test1.gz could only be replicated to 0 nodes instead of minReplication (=1). There are3 datanode(s) running and 3 node(s) are excluded in this operation.
事實上我的DataNode完全正常，我通過程式碼將本地檔案上傳到HDFS也成功了。說明hdfs正常，有沒有大神指導下這個是什麼錯誤。
