Neal Richardson commented on ARROW-10850: ----------------------------------------- Thanks for the report. Can you share a trivial file that reproduces this? > [R] Unrecognized compression type: LZ4 on Windows > ------------------------------------------------- > > Key: ARROW-10850 > URL: https://issues.apache.org/jira/browse/ARROW-10850 > Project: Apache Arrow > Issue Type: Bug > Components: R > Affects Versions: 2.0.0 > Environment: Windows 10, R 3.6.2, RStudio 1.3.1073 > Reporter: Chris Kennedy > Priority: Major > Labels: LZ4 > > Hello, > I have recently re-installed Arrow from CRAN in R 3.6.2 and it no longer can > import a feather file with LZ4 compression (whereas in previous months this > worked fine): > {code:java} > > data = suppressWarnings(arrow::read_feather("blah.feather")) > {code} > {noformat} > Error in ipc___feather___Reader__Read(self, columns) : Invalid: Unrecognized > compression type: LZ4{noformat} > I have attempted to install from source but continue to receive this error. > According to the documentation though shouldn't the CRAN package also have > LZ4 support? Is it possible that the CRAN build has lost LZ4 support? My > feather file was created in pandas. > If I install version 1.0.1 I can import the data correctly: > {code:java} > devtools::install_version("arrow", version = "1.0.1"){code} > Happy to send over any other information that could be helpful, and apologies > if I am making some mistake on my end. > Thanks, > Chris -- This message was sent by Atlassian Jira (v8.3.4#803005)
