YARN application container state doubt

[Prabhu Joseph]

Hi Experts,

   I have a Custom ApplicationMaster written using TWILL which asks for 20
Containers and RM ApplicationMasterService has assigned 20 containers out
of which 19 are moved from ACQUIRED to RUNNING. And there is one moved from
*ACQUIRED to COMPLETED. *
So my doubt is is ACQUIRED to COMPLETED a correct state flow and if so when
that will happen.


Thanks,
Prabhu Joseph
