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 and provide a method to allow
{{exitOnDispatchException}}/{{shouldExitOnError}} to be false to enable related
unit tests. There is no need for false value in a real daemon since daemons
should crash if its dispatcher quit.
# Make it default true instead of false, so that we don't need to hard code it
to be true in RM and NM, it is still configurable, and also provide method to
enable related unit tests.
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.

solutions:
# Remove the configuration item and provide a method to allow
{{exitOnDispatchException}}/{{shouldExitOnError}} to be false to enable related
unit tests, the assumption is there is no need for false value in a real
daemon, this is valid according to MAPREDUCE-3634 which introduce the
configuration item.
