> Key: IMPALA-11980
> URL: https://issues.apache.org/jira/browse/IMPALA-11980
> Project: IMPALA
> Issue Type: Sub-task
> Components: Clients
> Affects Versions: Impala 4.3.0
> Reporter: Joe McDonnell
> Priority: Major
>
> Various tests import code from the shell codebase:
> {noformat}
> $ git grep 'from shell\..*import'
> custom_cluster/test_hs2_fault_injection.py:from shell.ImpalaHttpClient import
> ImpalaHttpClient
> custom_cluster/test_hs2_fault_injection.py:from shell.impala_client import
> ImpalaHS2Client
> custom_cluster/test_hs2_fault_injection.py:from shell.shell_exceptions import
> HttpError
> custom_cluster/test_shell_interactive_reconnect.py:from shell.impala_shell
> import ImpalaShell as ImpalaShellClass
> shell/test_cookie_util.py:from shell.cookie_util import (cookie_matches_path,
> get_cookie_expiry,
> shell/test_shell_client.py:from shell.impala_client import
> ImpalaBeeswaxClient, ImpalaHS2Client
> shell/test_shell_commandline.py:from shell.impala_shell import ImpalaShell as
> ImpalaShellClass
> shell/test_shell_interactive.py:from shell.impala_shell import ImpalaShell as
> ImpalaShellClass{noformat}
> The shell codebase currently uses relative imports, so when using Python 3,
> the imports within the shell codebase will not work. For example,
> impala_shell.py includes compatibility.py via a relative import:
> {noformat}
> from compatibility import _xrange as xrange{noformat}
> In order for this to work under Python 3, these relative imports will need to
> be absolute. However, some ways of invoking the shell will fail with absolute
> imports (e.g. bin/impala-shell.sh). Other form factors are fine with absolute
> imports (e.g. pip installs into a venv).
