OrientDB ETL Throws exception on loading CSV file - csv

Question

I am trying to load a simple CSV file to OrientDB and it always throws this exception.
CSV File Content
id, name, role
1, Sarath, Architect
2, Anoop, Project Manager
3, Nazeem, Lead Developer
4, Rini, Senior Developer
5, Shine, iOS Developer
6, Vishnu, iOS Developer
json config file
{
"source": { "file": { "path": "./dev.csv" } },
"extractor": { "row": {} },
"transformers": [
{
"csv": {}
},
{ "vertex": { "class": "Person" } }
],
"loader": {
"orientdb": {
"dbURL": "remote:localhost/dev",
"dbType": "graph",
"dbUser": "root",
"dbPassword": "root",
"dbAutoCreate": true,
"classes": [
{"name": "Person", "extends": "V"}
], "indexes": [
{"class":"Person", "fields":["id:integer"], "type":"UNIQUE" }
]
}
}
}
All the time it shows this exception. I tried different CSV options but it did not work. Looks like the file reading itself throwing exception.

Answer 1

The stack trace gives you the cause of the problem (you only showed the first, not interesting lines in your example).
Check:
The server is running (you specified remote:localhost/dev, so the server must be running on the default port at the same machine).
The database exists and has "root" / "root" as credentials (note that mostly "admin" "admin" is used)
The file dev.csv is present in the current directory
Tried out your example and works without modification.

Answer 2

I had the same problem, and it was due to one of the directories in the path to the JSON config file having a space in it. The oetl script doesn't handle this well and thus can't find the script.
#rmuller: The OP showed the entire traceback. That's all you get in this case.
