-------------------------------------
Summary: TestAuthorizationProvider.test_invalid_provider_flag uses
Python 2.6 incompatible code
Key: IMPALA-9157
URL: https://issues.apache.org/jira/browse/IMPALA-9157
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 3.4.0
Reporter: Joe McDonnell
Assignee: David Knupp
Our Centos 6 builds use Python 2.6, which means that it doesn't have
check_output (added in Python 2.7). This causes test failures in
test_provider.py:
{noformat}
authorization/test_provider.py:70: in setup_method
self.pre_test_cores = set([f for f in possible_cores if is_core_dump(f)])
../lib/python/impala_py_lib/helpers.py:64: in is_core_dump
file_std_out = exec_local_command("file %s" % file_path)
../lib/python/impala_py_lib/helpers.py:34: in exec_local_command
return subprocess.check_output(cmd.split())
E AttributeError: 'module' object has no attribute 'check_output'{noformat}
This comes from the new code to handle intentional core dumps:
[https://github.com/apache/impala/blob/master/lib/python/impala_py_lib/helpers.py#L34]
{noformat}
def exec_local_command(cmd):
""" Executes a command for the local bash shell and return stdout as a
string.
Args:
cmd: command as a string
Return:
STDOUT
"""
return subprocess.check_output(cmd.split()){noformat}
