Wow, sorry about that - i truly thought Kevin was the only remaining ship-it

Review request for Aurora, Joshua Cohen, Kevin Sweeney, and Zameer Manji.


Bugs: AURORA-613
https://issues.apache.org/jira/browse/AURORA-613


Repository: aurora


Description
---

There's a lot going on here, i'm happy to break this up if you'd perfer, but 
the bulk of the change (JobUpdateControllerImpl+Test) would remain.

The remaining required piece here is to record JobInstanceUpdateEvents when 
actions are taken.

As you try to follow JobUpdateControllerImplTest, take some care to understand 
how FakeScheduledExecutor works.  Ultimately, it accepts work added to a mock, 
and executes that work when FakeClock is advanced past the scheduled time.  It 
may not be obvious at first, but be glad it's there - this kind of async test 
would be a nightmare without it.

Bugs: AURORA-613
https://issues.apache.org/jira/browse/AURORA-613


Repository: aurora


Description
---

There's a lot going on here, i'm happy to break this up if you'd perfer, but 
the bulk of the change (JobUpdateControllerImpl+Test) would remain.

The remaining required piece here is to record JobInstanceUpdateEvents when 
actions are taken.

As you try to follow JobUpdateControllerImplTest, take some care to understand 
how FakeScheduledExecutor works.  Ultimately, it accepts work added to a mock, 
and executes that work when FakeClock is advanced past the scheduled time.  It 
may not be obvious at first, but be glad it's there - this kind of async test 
would be a nightmare without it.

(Updated Sept. 16, 2014, 12:39 a.m.)


Review request for Aurora, Joshua Cohen, Kevin Sweeney, Maxim Khutornenko, and 
Zameer Manji.


Bugs: AURORA-613
https://issues.apache.org/jira/browse/AURORA-613


Repository: aurora


Description
---

There's a lot going on here, i'm happy to break this up if you'd perfer, but 
the bulk of the change (JobUpdateControllerImpl+Test) would remain.

The remaining required piece here is to record JobInstanceUpdateEvents when 
actions are taken.

As you try to follow JobUpdateControllerImplTest, take some care to understand 
how FakeScheduledExecutor works.  Ultimately, it accepts work added to a mock, 
and executes that work when FakeClock is advanced past the scheduled time.  It 
may not be obvious at first, but be glad it's there - this kind of async test 
would be a nightmare without it.

I take that back - tried this out, and there are some complications that i'd 
like to establish a pattern for before proceeding.
The biggest issue is that an exception surfacing from Service.startUp() results 
in a hang (if you follow the startAsync().awaitRunning() pattern).   This makes 
for difficult unit testing where you want things like AssertionErrors to 
surface.  I've left a TODO for now.

Two primary reasons:
- it minimizes the dependency exposure to InstanceActionHandler
- it clarifies that the function is already called in the context of a 
transaction

Sure.

Went with InstanceKeys.toString, since canonicalString bears more weight than 
i'm interested in here.

I'm torn here.  While i generally agree, this would mean hitting this condition 
is always dire, and likely requires code or data forensics to fix.  However, if 
we handle the situation gracefully, it's far less critical.

In other words, if i'm carrying the pager, i want this graceful degradation.

I've added stats to at least enable alerting here.

I'm slightly hesitatnt here.  There's non-trivial relationships between the 
fields in JobUpdateConfiguration, and i'm failing to extract the validation out 
in a way that doesn't leave me with 3 helper functions, some redundancy, and 
less certainty that the gates are in place.

I'd also like to see if the TODO about moving the logic to 
SchedulerThriftInterface pans out.

src/main/java/org/apache/aurora/scheduler/thrift/SchedulerThriftInterface.java


If I'm reading correctly there's no need to make this final



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Historically we've injected Storage and used the transaction API (and 
storeProvider.getTaskStore()) here, any reason to deviate from that?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateController.java


Is this just Guava Service#start()? Maybe implement that interface (by 
extending AbstractIdleService) here instead so that we get state monitoring and 
error detection for free, as well as future integration with AURORA-324.



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Factor out an InstanceKeys.canonicalString?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateEventSubscriber.java


This seems like a fatal startup error - should the scheduler process abort 
here?



src/main/java/org/apache/aurora/scheduler/updater/OneWayJobUpdater.java


redundant use of toString



src/main/java/org/apache/aurora/scheduler/updater/OneWayJobUpdaterFactory.java


TODO to use AssistedInject to generate this factory here?

Ship it!


Looks good to me, just a few minor questions/nits:


src/main/java/org/apache/aurora/scheduler/thrift/SchedulerThriftInterface.java


Is this a leftover from some intermediate work?



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Some more context to this log message might be helpful (akin to the 
KillTask log? `"Adding " + instance + " while " + status`



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Does it make sense to separate the config validation logic from the 
UpdateFactory creation?

Repository: aurora


Description
---

There's a lot going on here, i'm happy to break this up if you'd perfer, but 
the bulk of the change (JobUpdateControllerImpl+Test) would remain.

The remaining required piece here is to record JobInstanceUpdateEvents when 
actions are taken.

As you try to follow JobUpdateControllerImplTest, take some care to understand 
how FakeScheduledExecutor works.  Ultimately, it accepts work added to a mock, 
and executes that work when FakeClock is advanced past the scheduled time.  It 
may not be obvious at first, but be glad it's there - this kind of async test 
would be a nightmare without it.

Everything down from here deals with processing a MonitorAction acquired on 
this line and can technically be moved into its own method. That would reduce 
the recordAndChangeJobUpdateStatus() length and make it a bit more readable 
(i.e. easier to reason about the recursive way this funciton may be invoked).

A lower bound validation would not quite solve the problem as it still may not 
be enough to kill a task. I have routinely observed task kills taking longer 
than the default watch_secs value of 45 seconds. The current client timeout is 
set to 2.5 minutes of binary backoff countdown. I feel we should follow the 
same approach on the scheduler and perhaps expose an Arg to make it 
configurable.

Is there anything upstream that ensures the instance is still active though? Is 
that check part of the same transaction? I am concerned about the race between 
instance state and this query. Perhaps it's just safer to proceed with instance 
kill, which will be a no-op in this case.

I meant to point that ROLLING_BACK should be conditional upon the 
user-specified rollbackOnFailure config value. I could not find where it is 
honored.

Zameer Manji.


Bugs: AURORA-613
https://issues.apache.org/jira/browse/AURORA-613


Repository: aurora


Description
---

There's a lot going on here, i'm happy to break this up if you'd perfer, but 
the bulk of the change (JobUpdateControllerImpl+Test) would remain.

The remaining required piece here is to record JobInstanceUpdateEvents when 
actions are taken.

As you try to follow JobUpdateControllerImplTest, take some care to understand 
how FakeScheduledExecutor works.  Ultimately, it accepts work added to a mock, 
and executes that work when FakeClock is advanced past the scheduled time.  It 
may not be obvious at first, but be glad it's there - this kind of async test 
would be a nightmare without it.

Better yet - addressed TODO :-)

Negatory - i still need the exception to flag when 'updateOnlyTheseInstances' 
is invalid.  Though, i think all this validation should live together.  Added a 
TODO.

Sure, done.

Obviated by other changes.

Good question.  I've added a TODO, we should discuss later which should come 
first.

That's a precondition - this action should not be taken if the instance is not 
active.

I think a lower bound when validating is reasonable, but i don't like the idea 
of changing it silently.

Added.

Fixed.

Because the output should _always_ be ABORTED.  That map would mean "you can 
only go from aborted to aborted."

I wasn't able to follow your request, can you give some pseudocode to 
illustrate?

A fine suggestion!  It resulted in more code, but it's overall cleaner, thanks!

Nuked with switch to IInstanceKey.

Goes away now that switch statement is gone.

Whoops, that was a reminder for myself, fixed in this diff.  Removed TODO.

They're all accessors.  I've done a bit of collapsing, trying for a balance 
between more code and more DRY.

Thanks, i wasn't happy with this.  I've pushed more of this down into 
JobUpdateStateMachine.

Sure, done.  Downside is that we lose ability to use Functions.forMap().

I've refactored this to eliminate the fall-through branch.  Thanks for the 
nudge!

I revisited this and started using IInstanceKey, which is ~exactly what you're 
describing.  Thanks!

src/main/java/org/apache/aurora/scheduler/base/Query.java


typo



src/main/java/org/apache/aurora/scheduler/thrift/SchedulerThriftInterface.java


Consider discarding in favor of https://reviews.apache.org/r/25481/



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Should it rather be named ADD_TASK...? It's used for both update (replace) 
and add new instance but since KILL is separate feels like "ADD" should be more 
appropriate here (i.e. it only inserts pending and does not do any killing).



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Replace with instanceName.



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Will quota checking come later or you'd rather see AURORA-686 fixed instead?



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


This will throw unnecesserily if the instance is not in active state. I'd 
rather see an inactive instance get killed.



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


This value is user-controlled and might be set too low for the kill to 
succeed. Would it rather make sense to fix it internally (as it is now on the 
client)?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateController.java


Missing docs.



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


typo



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Why not just inline Functions.forMap(ImmutableMap.of(ABORTED, ABORTED)) 
instead?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Spent quite a bit of time reading this method. Would definitely benefit 
from refactoring. How about at least moving everything down from here to 
something like maybeEvaluateUpdater()?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Mind leaving a TODO here to create a getJobUpdate() storage API instead?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


+1



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Is active() deliberate here? If so, perhaps rename the function to 
"getActiveInstance" to clearly state its purpose?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


I a bit concerned about this circular dependency between evaluateUpdater 
and changeJobUpdateStatus  but not sure what would be the best way to break 
it... Hopefully there is enough checking in place to prevent looping.



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


This seems unconditional. Where does rollbackOnFailure get evaluated?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Would it make sense to have a catch-all else block here to log in case 
actions is empty?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateEventSubscriber.java


Logging try...catch around similar to taskChangedState()?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateEventSubscriber.java


Same here. System resume is notoriously hard to troubleshoot and we 
probably don't want to let it out uncaught.

Context: this has code coverage run without adding -Pq

Happy to pull this out for discussion in another review if you'd like.  
Basically, Maxim and i concluded that jacoco is a small overhead when compared 
to findbugs, and is a really important part of running unit tests.  When trying 
to converge a unit test to 100% coverage, running the extra checks is a big 
burden.

Maybe a method rather than a class?  The "/" is orthogonal to extracting a 
helper.  I don't care about formatting - just that logs have necessary context.

Yes.

There's another static import for another FAILED.

Maxim and i stepped on toes here, so this validation moves up the stack with

Some of these questions are probably non-sensical due to my limited 
understanding of the scheduler internals, apologies for that ;).


src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Instead of embedding the logic into a switch here, would it make sense to 
make InstanceAction an actual class that encapsulates the logic/defines an 
interface around performing these actions?



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


use instanceName here?



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Should we log (or assert?) here? Are there other actions that we're 
intentionally not processing, or is it an error if we get an action not covered?



src/main/java/org/apache/aurora/scheduler/updater/InstanceUpdater.java


Is there a ticket for this?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


I don't know if the amount of work done by the underlying calls warrants 
it, but you could DRY this up a bit by having instance vars for 
`storeProvider.getJobUpdateStore()` (used here, and above) and 
`update.getSummary()` (used twice below and once above). If you wanted to go 
completely overboard, `update.getSummary().getJobKey()` is used above and below.



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


It seems like the logic of what states to transition to from a given state 
is somewhat spread out over the codebase (c.f. 
https://reviews.apache.org/r/25300/diff/#)? Is there any way we can centralize 
that?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Thoughts on changing the Function here to be `Function>` to clean up the null dance below?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Do we need guards in place in case the updaterStatus here is not 
ROLLING_BACK or ROLLING_FORWARD (or is it guaranteed to be one of the two? If 
so, is there danger in the addition of additional statuses in the future 
rendering that assumption invalid?)

This matches the logic previously explained to me, but the diff is pretty 
large. Once my questions are answered I'll take another look before giving a 
ship it.


build.gradle


Is this needed? If so please break it out of this change.



src/main/java/org/apache/aurora/scheduler/updater/InstanceActionHandler.java


Would it be a bad idea to encapsulate this into a InstanceName class that 
contains the logic for constructing one from JobKey + instanceId and how to 
render it to a String?

It seems like a bit of overkill but I dislike the + "/" in the code.



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Just to be clear, currently-active updaters are also persisted in storage 
right?



src/main/java/org/apache/aurora/scheduler/updater/JobUpdateControllerImpl.java


Shouldn't this just be FAILED?



src/main/java/org/apache/aurora/scheduler/updater/OneWayJobUpdaterFactory.java


How are these errors going to be surfaced to the user?
