Description

 

 

The write_feather and write_parquet functions don't seem to follow the R umask settings. Please let me know if you need any other information from me to replicate or document this issue. Thanks!

Code to replicate bug:

 

library(arrow)
Sys.umask(mode = "2")
Sys.umask()

arrow::write_feather(x = cars, sink = "~/test.feather")
arrow::write_parquet(x = cars, sink = "~/test.parquet")
write.csv(x = cars, file = "~/test.csv")

system("ls -l ~/test.feather")
system("ls -l ~/test.parquet")
system("ls -l ~/test.csv")

sessionInfo()

Full output:
