我刚刚使用以下ETL配置创建了一个自定义数据库,
{
"source": { "file": { "path": "./mydata.csv" } },
"extractor": { "row": {} },
"transformers": [
{ "csv": {} },
{ "vertex": { "class": "MyClass" } }
],
"loader": {
"orientdb": {
"dbURL": "plocal:/opt/orientdb/databases/MyData",
"dbUser": "root",
"dbPassword": "qrefhiuqwriouhwqv",
"dbType": "graph",
"classes": [
{"name": "MyClass", "extends": "V"},
]
}
}
}
现在,当我进入Web控制台时,我可以看到我在数据库MyData中创建了433k类型的MyClass记录。
当我尝试使用&#34进行查询时;从MyClass"中选择,我收到错误
2015-04-06 23:56:25:541 SEVERE Internal server error:
com.orientechnologies.orient.server.distributed.ODistributedException:
No nodes configured for partition 'MyClass.[]' request:
id=-1 from=node1428362873334 task=command_sql(select from MyClass) userName= [ONetworkProtocolHttpDb]
我做错了什么?
