             Summary: [R] Installation on RHEL 7 Cannot call io___MemoryMappedFile__Open()
                 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


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___MemoryMappedFile__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___MemoryMappedFile__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 io___MemoryMappedFile__Open(){color} }}on{{ {color:#de350b}read_parquet{color}}}
