-----------------------------------
(Really we could say it's a duplicate of
https://issues.apache.org/jira/browse/SPARK-26995 )
> Missing library for reading/writing Snappy-compressed files
> -----------------------------------------------------------
>
> Key: SPARK-28981
> URL: https://issues.apache.org/jira/browse/SPARK-28981
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 2.4.4
> Reporter: Paul Schweigert
> Priority: Minor
>
> The current Dockerfile for Spark on Kubernetes is missing the
> "ld-linux-x86-64.so.2" library needed to read / write Snappy-compressed
> files.
>
> Sample error message when trying to read a parquet file compressed with
> snappy:

> The relevant library is in the Alpine Linux "gcompat" package
> ([https://pkgs.alpinelinux.org/package/edge/community/x86/gcompat]). Adding
> this library to the Dockerfile enables the reading/writing of
> Snappy-compressed files.
