Allen Wittenauer commented on HADOOP-13035:
-------------------------------------------
Can't happen.
YARN has two modules that take 1 hour each (hadoop-yarn-server-resourcemanager
and hadoop-yarn-server-resourcemanager). MR has one module that takes two
hours (hadoop-mapreduce-client-jobclient).... and that's for a single JVM. It
simply isn't realistic to run the full gamut of unit tests as part of
precommit. Either someone needs to spend time working on MAPREDUCE-6674 and
YARN-4950 and probably follow-ons to at least cut the times for all these
modules in half or someone needs to double the amount of build resources
available at Apache so that we can have longer run times.

> As per the discussion in YARN-3971 the we should be setting the service state
> to STARTED only after serviceStart()
> Currently {{AbstractService#start()}} is set
> {noformat}
> if (stateModel.enterState(STATE.STARTED) != STATE.STARTED) {
> try {
> startTime = System.currentTimeMillis();
> serviceStart();
> ..
> }
> {noformat}
> enterState sets the service state to proposed state. So in
> {{service.getServiceState}} in {{serviceStart()}} will return STARTED .
