> Toolchain Python missing readline support
> -----------------------------------------
>
> Key: IMPALA-9686
> URL: https://issues.apache.org/jira/browse/IMPALA-9686
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 4.0
> Reporter: Laszlo Gaal
> Assignee: Laszlo Gaal
> Priority: Critical
> Fix For: Impala 4.0
>
>
> Toolchain Python (made default by IMPALA-9626) is missing readline support.
> When run via
> {{impala-python}}, the up arrow just prints control characters instead of
> retrieving earlier input. Also, "{{import readline}}" throws an error.
> All the above works when executed in system Python.
> This is most disturbing when encountered in the Impala shell invoked from a
> development environment.
> *Workaround:*
> $IMPALA_HOME/infra/python/env/bin/pip install readline
