Yaguang Jia commented on KYLIN-5434:
------------------------------------
h2. Fix Design:
When restarting a task, kill yarn on the task is executed first, at this time
the driver process has not been killed off, it will receive an exception and
thus send a request to the KE process to update the stage state process. This
is not an expected update and should be intercepted.
h3. To do this.
Before restarting the task, record the task into the ExecutableContext's
frozenJobs collection, meaning that the task is in restart and should not be
operated on until the restart process of the task is finished. Just remove it
from the frozenJobs when the restart is finished. In addition, when updating
the service of the stage, you need to determine whether the current task is in
the frozenJobs collection, and if it is, it will not be updated. If it is, then
it will not be updated. If it is not in the frozenJobs collection, then it will
be updated.
