> recently , while the hadoop cluster are working .Sometime , there has no any errors in
the RM or NM , but the RM do not assigin resource while remaining much resource in the cluster
.The following representation are 
> 1、the command line such as "yarn node -list " could execute .The result are all well.
> 2、all nodes with running containers are all the MRapp container , no yarnchild process
is running . 
> 3、all applications that had been submited to the cluster early are all in the progress
of 5%  ,simultanously they will hang forever.
> the key is that we can not find any error or exception , but the applications  hung.
> The temporary solution is to switch the active resourcemanager,but  where is the problem???Could
you give some advices?
