Description
Hello again! I have another minor R arrow issue.
The ParquetFileWriter docs say that the sink argument can be a "string which is interpreted as a file path". However, when I try to use a string, I get a segfault because the memory isn't mapped.
Maybe this is a separate request, but it would also be helpful to have documentation for the methods of the writer created by ParquetFileWriter$create().
Docs link: https://arrow.apache.org/docs/r/reference/ParquetFileWriter.html
library(arrow) sch = schema(a = float32()) writer = ParquetFileWriter$create(schema = sch, sink = "test.parquet") #> *** caught segfault *** #> address 0x14100007d, cause 'memory not mapped' #> #> Traceback: #> 1: parquet___arrow___ParquetFileWriter__Open(schema, sink, properties, arrow_properties) #> 2: shared_ptr_is_null(xp) #> 3: shared_ptr(ParquetFileWriter, parquet___arrow___ParquetFileWriter__Open(schema, sink, properties, arrow_properties)) #> 4: ParquetFileWriter$create(schema = sch, sink = "test.parquet") # This works as expected: sink = FileOutputStream$create("test.parquet") writer = ParquetFileWriter$create(schema = sch, sink = sink)
