>
> *Env :*
> Server OS :- UBUNTU
> No. of Cluster Node:- 9120 NMs
> Env Mode:- [Secure / Non secure]Secure
> *Preconditions:*
> ~9120 NM's was running
> ~1250 applications was in running state
> 35K applications was in pending state
> *Test Steps:*
> 1. Submit the application from 5 clients, each client 2 threads and total 10
> queues
> 2. Once application submittion increases (for each application of
> distributted shell will call getClusterNodes)
> *ClientRMservice#getClusterNodes tries to get
> ClusterNodeTracker#getNodeReport where map nodes is locked.*
