Neal Richardson commented on ARROW-7807:
----------------------------------------
Is there a minimal rhel-7 Docker image with R we can test with? (R-hub only has
rhel-6.)
I'm not sure how to diagnose from a distance why the system packages you said
you installed aren't being found.
FWIW, there's a new 0.16.0.1 release on CRAN, and I suspect that the default
behavior of building Arrow C++ from source as part of
{{install.packages("arrow")}} should work this time. Can you try that? If so,
that should unblock you for now, and then if we can add a Docker image to our
build matrix that reproduces the issue you experienced, we might be able to fix
it.

> Key: ARROW-7807
> URL: https://issues.apache.org/jira/browse/ARROW-7807
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Affects Versions: 0.16.0
> Environment: RHEL 7.6
> Custom R build in a non-default location
> Reporter: Omar Yassin
> Priority: Major
>
> Hey Team,
> I've been using Arrow successfully in python through conda and have been able
> to write and read parquet files successfully. Now I'm trying to have R users
> consume some of the parquet files I've produced. They run a shared R build in
> a custom location, so can't use conda with their setup. We tried installing
> the C++ libraries system-wide and then the R library in a user's directory,
> but kept getting {color:#de350b}Cannot call
> io{color}{color:#de350b}{{__MemoryMappedFile_}}{color}{color:#de350b}Open()
> {color}errors on{color:#de350b} read_parquet(){color}. I'm not sure if we've
> missed a step, or where to continue debugging. Does the R package have any
> known issues on RHEL 7? Below are some details:
>
> Environment:
> * RHEL 7.6
> * Custom local R environment in a non-default location
> Steps taken:
> # Installed the C++ libraries first (now live in /usr/lib64) as described
> (v.0.16.0) in [https://arrow.apache.org/install/]
> # Ran {color:#de350b}{{install.packages('arrow')}}{color} in an interactive
> R session
> # It couldn't find the C++ libraries and said {{{color:#de350b}No C++
> binaries found for rhel-7{color}}}
> # Couldn't find
> [https://dl.bintray.com/ursalabs/arrow-r/libarrow/bin/rhel-7/arrow-0.16.0.zip]
> when it tried to pull the binaries
> # Source download didn't work due to internal github firewall rules
> # Installed without errors, but threw {{{color:#de350b}Cannot call
> io{color}}}{color:#de350b}{{__MemoryMappedFile_}}{color}{{{color:#de350b}Open(){color}}}
> error on {{{color:#de350b}read_parquet(){color}}}
> # Removed the rlib/arrow directory and tried a different route
> # Set {{{color:#de350b}LIBARROW_BINARY_DISTRO='centos-7'{color}}}
> # Set {{{color:#de350b}PKG_CONFIG=/usr/lib64{color}}}
> # Ran {color:#de350b}{{install.packages('arrow')}}{color} in an interactive
> R session
> # Binaries and package seemed to install correctly without complaints
> # Still threw {{{color:#de350b}Cannot call
> {color}}}{color:#de350b}{{io__MemoryMappedFile_Open{{{color:#de350b}(){color}
> on {color:#de350b}read_parquet{color}}}}}{color}
