>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager
>    Affects Versions: 0.23.4
>            Reporter: Robert Joseph Evans
>
> The NodeManager should limit the number of applications that have their logs 
> being aggregated in parallel.  This will reduce the load on the NN.  We need 
> to ensure that the RM will continue to renew the token while this is 
> happening.  We also should look if the NM starts to fall behind if it can 
> delete some of the logs or not.
