-------------------------------------
Summary: add IGNORED status to Coordinator to allow removing Coord
job from Bundle in runtime
Key: OOZIE-1791
URL: https://issues.apache.org/jira/browse/OOZIE-1791
Project: Oozie
Issue Type: Bug
Reporter: Ryota Egashira
data pipeline customers need clean way to remove coord job from bundle job in
runtime.
currently to make a change to coordinator after bundle submission, it is
required to relaunch entire bundle after fixing coord xml or run another bundle
with new coord. OOZIE-1769 to support changing coord properties in runtime. in
many scenarios, customers want to remove the coord from the bundle first, and
fix the coord, put it back, without stopping entire bundle job.
suggested approach is to add IGNORED status to Coord Job/Actions. once CLI
command to remove coord job from bundle issued, change status of coord
job/actions to IGNORED (probably bundle aciton, too). If one of coordinators
in the bundle has IGNORED status, then the status of the bundle would be
RUNNING, not RUNNINGWITHERROR. (StatusTransitService need to be changed for
couple of other cases).
Only coord job/actions in terminal state (SUSPENDED, KILLED or FAILED) can be
changed to IGNORED. PREP, RUNNING, WAITING or SUCCEEDED ones cannot be changed.
We'd like to have discussion on this approach before proceed. Any feedback
appreciated.
