{code}

    if b.startswith('/'):
AttributeError: 'NoneType' object has no attribute 'startswith'
{code}

The error looks to be due to lzo changes, as the following code has the issue:
{code}
# if enabled, LZO GPL libraries must be copied as well
     91   if lzo_utils.should_install_lzo():
     92     stack_root = Script.get_stack_root()
     93     tez_version = component_version.get_component_repository_version("TEZ")
     94     hadoop_lib_native_lzo_dir = os.path.join(stack_root, tez_version, "hadoop", "lib", "native")
     95
{code}
