Jonathan Keane commented on ARROW-8726:
---------------------------------------
This was with the release version. I'm working on getting the development
version installed to try it there.
> [R][Dataset] segfault with a mis-specified partition
> ----------------------------------------------------
>
> Key: ARROW-8726
> URL: https://issues.apache.org/jira/browse/ARROW-8726
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Reporter: Jonathan Keane
> Assignee: Francois Saint-Jacques
> Priority: Major
> Fix For: 0.17.1
>
>
> Calling filter + collect on a dataset with a mis-specified partitioning
> causes a segfault. Though this is clearly input error, it would be nice if
> there was some guidance that something was wrong with the partitioning.
> {code:r}
> library(arrow)
> library(dplyr)
> dir.create("multi_mtcars/one", recursive = TRUE)
> dir.create("multi_mtcars/two", recursive = TRUE)
> write_parquet(mtcars, "multi_mtcars/one/mtcars.parquet")
> write_parquet(mtcars, "multi_mtcars/two/mtcars.parquet")
> ds <- open_dataset("multi_mtcars", partitioning = c("level", "nothing"))
> # the following will segfault
> ds %>%
> filter(cyl > 8) %>%
> collect()
> {code}
