Description

I am writing this as an FYI because it caught me today. My hope is that maybe this will one day help solve a bug or act as a clue if/when you encounter this behaviour. I don't have any time at the moment to track exactly what is happening so unfortunately I am just sharing as is. The issue is when one loads the R.utils package after loading arrow. Again likely this is an issue related to R.utils and therefore not strictly a bug in arrow. Still thought it would be useful to share:

 

library(arrow)
#> 
#> Attaching package: 'arrow'
#> The following object is masked from 'package:utils':
#> 
#> timestamp
write_parquet(iris, 'iris.parquet')
pq <- ParquetFileReader$create('iris.parquet')
library(R.utils)
#> Loading required package: R.oo
#> Loading required package: R.methodsS3
#> R.methodsS3 v1.8.0 (2020-02-14 07:10:20 UTC) successfully loaded. See ?R.methodsS3 for help.
#> R.oo v1.23.0 successfully loaded. See ?R.oo for help.
#> 
#> Attaching package: 'R.oo'
#> The following object is masked from 'package:R.methodsS3':
#> 
#> throw
#> The following objects are masked from 'package:methods':
#> 
#> getClasses, getMethods
#> The following objects are masked from 'package:base':
#> 
#> attach, detach, load, save
#> R.utils v2.9.2 successfully loaded. See ?R.utils for help.
#> 
#> Attaching package: 'R.utils'
#> The following object is masked from 'package:arrow':
#> 
#> timestamp
#> The following object is masked from 'package:utils':
#> 
#> timestamp
#> The following objects are masked from 'package:base':
#> 
#> cat, commandArgs, getOption, inherits, isOpen, nullfile, parse,
#> warnings
pq <- ParquetFileReader$create('iris.parquet')
#> Error in exists(name, envir = envir, inherits = FALSE): use of NULL environment is defunct
