   have spend more time on this. the issue is due to the double close called 
from:
   1. ParquetFileWriter::end (the finally block calls close)
   2. ParquetFileWriter::close tries to close PositionOutputStream using the 
try-with-resources block.
   3. InternalParquetRecordWriter::close calls ParquetFileWriter::end and in 
finally block AutoCloseables.uncheckedClose, which calls 
ParquetFileWriter::close the 2nd time.
   
   looks like ParquetFileWriter::close might require protection against double 
close.
