Problems to ingest spatial dimensions

Hi, list.

I’m trying to ingest some data and put latitude and longitude as spatial dimensions but when the ingestion process is done, I can’t see latitude, longitude or coordinates (dimName) in segment details at druid coordinator console. I’m using druid 0.9.1 and ingestion was hadoop batch.

My parserSpec is:

“parser”: {
“type”: “hadoopyString”,
“parseSpec”: {
“format”: “json”,
“timestampSpec”: {
“column”: “timestampColumn”,
“format”: “auto”
},
“dimensionsSpec”: {
“dimensions”: [“a”, “b”],
“dimensionExclusions”: ,
“spatialDimensions”: [{
“dimName”: “coordinates”,
“dims”: [“latitude”, “longitude”]
}]
}
}
}

Is there something wrong with this spec?
