Yufei Gu commented on YARN-6522:
--------------------------------
# Patch v3 fixes style issue.
# YARN-6506 is for the bugs found by findbugs.
# The unit test failure is caused by rumen input format, which doesn't work for
a long time. YARN-6111 is the jira to track that issue.
> Make SLS JSON input file format simple and scalable

> 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. To specify the number of task for 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.
