Siddharth Seth updated TEZ-2798:
--------------------------------
Attachment: TEZ-2798.1.ignoredTemporarilyActivated.txt
Simple patch to fix the failing tests. The appContext was being passed to the
TaskCommContext before it was initialized in the DAGAppMaster. Uncommented the
ignores temporarily for jenkins.
bq. TEZ-2045 reversed the flow of sending taskspec to the communicator. This
ends up with the side effect that that container lifecycle becomes disconnected
from task lifecycle. Even if the container is in launching state, the rest of
the task state machine can proceed because there are no further interactions
with the AMcontainer object after that (in the no-error case).
Didn't quite understand this, or the significance w.r.t this jira. The state
machines could always run independently - with the interaction point being when
a remote container asked for a task. With the TezTaskComm - that remains
unchanged.
