             Summary: 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


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.
