I think I see the problem. The dependency readiness evaluation is checking
whether the number of ready containers is less than the number of desired
containers. But the number of desired containers is not being set until a flex
event is issued for the component, so we are checking that the number of ready
containers is not less than 0. I think we can fix this by initializing the
number of desired containers in the Component constructor.

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Rohith Sharma K S
> Priority: Major
>
> It is observed that transitive dependencies are not resolved as a result one
> of the component is started earlier.
> Ex : In HBase app,
> master is independent component,
> regionserver is depends on master.
> hbaseclient depends on regionserver,
> but I always see that HBaseClient is launched before regionserver.
