Description

Format of results for Druid Timeseries queries is as follows:

[
  {
    "timestamp": "2012-01-01T00:00:00.000Z",
    "result": { "sample_name1": 0, "sample_name2": 1.0, "sample_divide": 2.2222 } 
  },
  {
    "timestamp": "2012-01-02T00:00:00.000Z",
    "result": { "sample_name1": 2, "sample_name2": 3.32, "sample_divide": 4 }
  }
]

Out of this query results, we will generate Hive records with the following format:

[ new TimestampWritable(new Timestamp(1325376000000L)), new LongWritable(0), new FloatWritable(1.0F), new FloatWritable(2.2222F) ]
[ new TimestampWritable(new Timestamp(1325462400000L)), new LongWritable(2), new FloatWritable(3.32F), new FloatWritable(4F)]
