Have some trouble in querying json files

[????????]

hi,
When I use drill to query json files , error occurs . here is my error report :



and my drill storage-engines.json configuration :
{
  "storage":{
    "parquet-local" :
      {
        "type":"parquet",
        "dfsName" : "file:///"
      },
    "parquet-cp" :
      {
        "type":"parquet",
        "dfsName" : "classpath:///"
      },
    "jsonl" :
      {
        "type":"json",
        "dfsName" : "hdfs://localhost:9000/user/bevin"
      },
    "json-cp" :
      {
        "type":"json",
        "dfsName" : "classpath:///"
      },
    "parquet" :
      {
        "type":"parquet",
        "dfsName" : "hdfs://localhost:9000/user/bevin"
      }
  }
}



I also have some trouble in querying csv file. How should I config my drill 
storage-engines.json file?
thanks
