Right, but do you need the rest of the config at the top of the dfs default
config? Here's what I assume to be the full config taken from my 1.17 dfs
config (with other formats deleted):
{
"type": "file",
"connection": "file:///",
"config": null,
"workspaces": {
"tmp": {
"location": "/tmp",
"writable": true,
"defaultInputFormat": null,
"allowAccessOutsideWorkspace": false
},
"root": {
"location": "/",
"writable": false,
"defaultInputFormat": null,
"allowAccessOutsideWorkspace": false
}
},
"formats": {
"json": {
"type": "json",
"extensions": [
"json"
]
}
},
"enabled": true
}
