BytesWritable is not in parquet 's writePrimitive method in DataWritableWriter class

I have 2 int fields and 1 string field . To insert it into parquet File I use 2 IntWritable and 1 BinaryWritable object .

For next record i can reuse my 2 IntWritable objects but i have to create a new BinaryWritable object because BinaryWritable do not have set method . This is a bottleneck for me in performance as i am doing new again for every nextrecord .

How do you guys recommend i solve this since BytesWritable is not in parquet 's writePrimitive in DataWritableWriter class . it has ByteWritable and we need BytesWritable

首先阅读 DataWritableWriter.writePrimitive 及其对 ByteWritable 的处理，然后将其与 issue 中描述的 BytesWritable 和 BinaryWritable 用法进行比较。检查现有的 writer 测试是否覆盖 writable 二进制值；完成的定义应为支持可复用的 BytesWritable 输入，而无需为每条记录创建新的二进制对象。
