我正在使用DSE图形加载器将数据从CSV文件加载到DSE图。尝试使用DSE图形加载器加载数据时出现错误 - DSE图未配置为处理查询
我做了以下步骤来加载数据 -
创建的图形:
system.graph('followTopic').create()
设置别名:
:remote config alias g followTopic.g
创建以下模式:
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
…
然后在运行graphloader命令我得到下面提到的错误 -
./graphloader ../followTopinMapping.groovy -filename ../follow.csv -graph followTopic -address localhost
异常错误消息:
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)

关于错误消息“DSE图形没有被配置为处理查询”什么做我需要为DSE格拉夫装载机配置加载数据中DSE图表?
