format:
{code}
[ new LongWritable(1377907200000L), new Text("dim1_val"), new
LongWritable(111), new FloatWritable(10669F), new
FloatWritable(96.11711711711712F) ]
[ new LongWritable(1377907200000L), new Text("another_dim1_val"), new
LongWritable(88), new FloatWritable(28344F), new
FloatWritable(322.09090909090907F) ]
[ new LongWritable(1377907200000L), new Text("dim1_val3"), new
LongWritable(70), new FloatWritable(871F), new
FloatWritable(12.442857142857143F) ]
[ new LongWritable(1377907200000L), new Text("dim1_val4"), new
LongWritable(62), new FloatWritable(815F), new
