Yufei Gu updated YARN-6202:
---------------------------
Description:
Dispatcher.DISPATCHER_EXIT_ON_ERROR_KEY (yarn.dispatcher.exit-on-error) always
be true no matter what value in configuration files. This misleads users. Two
solutions:
# Remove the configuration item but also allow it to be false to enable some
unit tests, the assumption is there is no need for false value in product env.
# Make it default true instead of false, so that we don't need to hard code in
RM and NM, it is still configurable.
Other than that, the code around it needs to refactor. {{public static final}}
for a variable of interface isn't necessary, and YARN related configure item
should be in class YarnConfiguration.
> Configuration item Dispatcher.DISPATCHER_EXIT_ON_ERROR_KEY is disregarded
