----------------------------------
Summary: Suspend/Resume Hadoop Jobs
Key: YARN-2172
URL: https://issues.apache.org/jira/browse/YARN-2172
Project: Hadoop YARN
Issue Type: New Feature
Components: resourcemanager, webapp
Affects Versions: 2.2.0
Environment: CentOS 6.5, Hadoop 2.2.0
Reporter: Richard Chen
Fix For: 2.2.0
In a multi-application cluster environment, jobs running inside Hadoop
application may be of lower-priority than jobs running inside other
applications 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.
