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???
