Yufei Gu updated YARN-6522:
---------------------------
Description:
SLS input format is verbose, and it doesn't scale out. We can improve it in
these ways:
# We need to configure tasks one by one if there are more than one task in a
job, which means the job configuration usually includes lots of redundant
items. Specify the number task for a task configuration will solve this issue.
# Container host is useful for locality testing. It is obnoxious to specify
container host for each task for tests unrelated to locality. We would like to
make it optional.
# For most tests, we don't care about job.id. Make it optional and generated
automatically by default.
# job.finish.ms doesn't make sense, just remove it.
# container type and container priority should be optional as well.
