嘗試使用DSE圖形加載器加載數據時出現錯誤 - DSE圖未配置爲處理查詢

Question

我正在使用DSE圖形加載器將數據從CSV文件加載到DSE圖。

我做了以下步驟來加載數據 -

創建的圖形：

system.graph('followTopic').create() 

設置別名：

:remote config alias g followTopic.g 

創建以下模式：

schema.propertyKey("id").Text().single().create() 
schema.propertyKey("follower").Text().single().create() 
schema.propertyKey("name").Text().single().create() 
schema.propertyKey("type").Text().single().create() 
schema.propertyKey("followed").Text().single().create() 
schema.propertyKey("timestamp").Timestamp().single().create() 
schema.vertexLabel("record").partitionKey("id").create() 
schema.vertexLabel("user").properties("name").create()` 

映射文件：

// CONFIGURATION 

// Configures the data loader to create the schema 
config create_schema: false, load_new: true, load_threads: 3 

// DATA INPUT 
// Define the data input source (a file which can be specified via command line arguments) 
// inputfiledir is the directory for the input files 

inputfiledir = '/home/adminuser/data/' 
followTopic = File.csv(inputfiledir + "follow.csv").delimiter(',') 

//Specifies what data source to load using which mapper (as defined inline) 

load(followTopic).asVertices { 
    label "record" 
    key "id" 
} 

的我用CSV是：

id,follower,followed,type,timestamp 
1,@20cburns,topic_/best-friend,topic,5/7/2016 11:03:42 PM +00:00 
2,@68,topic_/tears-fall,topic,5/3/2016 2:20:01 AM +00:00 
3,@abba,topic_/best-friend,topic,6/15/2016 4:08:24 PM +00:00 
… 

然後在運行graphloader命令我得到下面提到的錯誤 -

./graphloader ../followTopinMapping.groovy -filename ../follow.csv -graph followTopic -address localhost 

異常錯誤消息：

2016-08-22 14:18:00 ERROR DataLoaderImpl:519 - Graph driver attempts exceeded for this operation, logging failure, but no records are present (may have been a schema operation)

關於錯誤消息「DSE圖形沒有被配置爲處理查詢」什麼做我需要爲DSE格拉夫裝載機配置加載數據中DSE圖表？

Answer 1

得到DataStax的幫助，讓這項工作。

其實一些設置已在集羣上搞砸了，所以我們就創建了一個新的羣集，然後只是做了一個設定，以使在/ etc /默認/ DSE文件 - 這個集羣的節點上的DSE圖表服務

GRAPH_ENABLED=1 

該更新架構的後 -

schema.propertyKey("id").Text().single().create() 
schema.propertyKey("follower").Text().single().create() 
schema.propertyKey("name").Text().single().create() 
schema.propertyKey("type").Text().single().create() 
schema.propertyKey("followed").Text().single().create() 
schema.propertyKey("timestamp").Timestamp().single().create() 
schema.vertexLabel("record").partitionKey("id").properties("follower", "name", "type", "followed", "timestamp").create() 

另外，關於時間戳應該是一個數字值，它通過DSE Graphloader被成功加載。

完成這些更改後，我可以通過DSE Graphloader成功加載數據。
