----------------------------------------------
Summary: Crash when reading empty .feather file
Key: ARROW-14344
URL: https://issues.apache.org/jira/browse/ARROW-14344
Project: Apache Arrow
Issue Type: Bug
Components: Python, R
Affects Versions: 5.0.0
Environment: Ubuntu Server 20.04.3, arrow (R) 5.0.02, pyarrow 3.0.0
(Python), RStudio 1.4.1717, R 4.1.0
Reporter: Reinier van Linschoten
I get an R Session Error in RStudio Server when I try to read an empty .feather
file.
Error: The previous R session was abnormally terminated due to an unexpected
crash. You may have lost workspace data as a result of this crash.
Reproduce:
* Create empty pandas dataframe in Python
* Write to .feather file with .reset_index(drop=True) and
compression="uncompressed"
* Try to read data in RStudio with arrow::read_feather(path)
* Error
I can read dataframes with one or more rows in RStudio.
I can read the empty dataframe with pandas.read_feather(). This returns an
empty pandas dataframe.
