Question

I'm attempting to test ArangoDB with its Java driver. I'm testing it on CentOS 6.6. I've been getting the following error: 

15:48:01.151 [main] DEBUG com.arangodb.http.HttpManager - [REQ]http-POST: url=http://127.0.0.1:8529/_api/gharial?waitForSync=true, headers=null, body={"name":"test","edgeDefinitions":[{"collection":"FriendsWith","from":["Profile"],"to":["Profile"]}],"orphanCollections":[]}

I've attempted to reboot the service as well as reinstalling. The log file contains the following lines:

The user has removed is system _graphs collection which is used for graph management inside of ArangoDB.

The corrosponding error message was a bit confusing and was improved with a newer ArangoDB version.

The solution was to recreate the the collection by specifying it will be a system collection : 

db._create("_graphs", {isSystem: true})
