Wangda Tan commented on YARN-6033:
----------------------------------
[~vvasudev],
While doing test for YARN-6223 (based on this patch). I think there's a minor
change needed:
In "container-executor.c", it has following statement:
{code}
executor_cfg = *(get_configuration_section("", &CFG)));
{code}
However if we have a config file doesn't has key/value under default section,
such as an empty config file, or file like:
{code}
[named-section]
k=v
{code}
The returned value of {{get_configuration_section("", &CFG)}} will be NULL
which will cause process crash without proper error message.
To fix the problem, we can:
1) Set an empty/NULL value to executor_cfg. Probably we should change
executor_cfg to a pointer.
2) By default create an empty value (not null) section in struct configuration.
Thoughts?
