Richard Chen updated YARN-2172:
-------------------------------
Description:
In a multi-application cluster environment, jobs running inside Hadoop YARN may
be of lower-priority than jobs running outside Hadoop YARN like HBase. To give
way to other higher-priority jobs inside Hadoop, a user or some cluster-level
resource scheduling service should be able to suspend and/or resume some
particular jobs within Hadoop application.
When target jobs inside Hadoop are suspended, those already allocated and
running task containers will continue to run until their completion or active
preemption by other ways. But no more new containers would be allocated to the
target jobs. In contrast, when suspended jobs are put into resume mode, they
will continue to run from the previous job progress and have new task
containers allocated to complete the rest of the jobs.
