cannot write more then once

[thomascool]

based on the example on the readme:

var parquet = require('node-parquet');

var schema = {
small_int: {type: 'int32', optional: true},
big_int: {type: 'int64'},
my_boolean: {type: 'bool'},
name: {type: 'byte_array', optional: true},
};

var data = [
[ 1, 23234, true, 'hello world'],
[ , 1234, false, ],
];

var writer = new parquet.ParquetWriter('my_file.parquet', schema);
writer.write(data);
writer.close();

Here will be the output:

$ ./node_modules/node-parquet/bin/parquet.js cat ./my_file.parquet
[1,23234,true,"hello world"]
[null,1234,false,null]

If write it three times like below:
writer.write(data);
writer.write(data);
writer.write(data);
writer.close();

The output will be nulls after first write:
$ ./node_modules/node-parquet/bin/parquet.js cat ./my_file.parquet
[1,23234,true,"hello world"]
[null,1234,false,null]
[null,null,null,null]
[null,null,null,null]
[null,null,null,null]
[null,null,null,null]
