Liwei Lin updated SPARK-15765:
------------------------------
Description:
Currently there are some code duplicates in continuous Parquet writes (as in
Structured Streaming) and non-continuous writes; see
[ParquetFileFormat#prepareWrite()|(https://github.com/apache/spark/blob/431542765785304edb76a19885fbc5f9b8ae7d64/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetFileFormat.scala#L68]
and
[ParquetFileFormat#ParquetOutputWriterFactory|https://github.com/apache/spark/blob/431542765785304edb76a19885fbc5f9b8ae7d64/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetFileFormat.scala#L414].
This may lead to inconsistent behavior, when we only change one piece of code
but not the other.
