So I changed into 'graph' (database type) and tried.
And the error message says "The process cannot access the file because
another process has locked a portion of the file."
Thus, from the source section on json file, I have changed "lock" to false
instead true. NOW IT SEEMS RUNNING BUT FAILED TO FULLY OPERATED.
Got a new error that saying, "the class 'Politician' does not extend class
'V' and therefore cannot be considered a Vertex."
I have created class 'Agent' extends class 'V', then created class
'Politician' extends class 'Agent'.
How should I change the following (bold) area. Please help me sir...
{
"config": {
"log": "debug"
},
"begin": [
],
"source": {
"file": { "path": "politician_sample.json", "lock": false }
},
"extractor": {
"json": {}
},
"transformers": [
* { "vertex": { "class": "Politician"}}*
],
"loader": {
"orientdb": {
"dbURL": "plocal:../databases/AgentDatabase_Document",
"dbUser": "admin",
"dbPassword": "admin",
"dbAutoCreate": false,
"standardElementConstraints": false,
"tx": false,
"batchCommit": 1000,
"dbType": "graph",
* "classes": [{ "name": "Politician", "extends": "Agent" } ],*
"indexes": [{ "class": "Politician", "fields": ["name:string"],
"type":"NOTUNIQUE_HASH_INDEX" }]
}
}
}
