   Thanks @avijayanhwx for the review!
   > In your setup, is the OOM caused due to multiple reports being bottlenecked at the event queue layer?
   
   yes, when there is a large number of containers(in my cluster ,  about 1 million containers), if datanode always send full report, the single thread report handler may not handle this stress, so there will be more and more container report wait for handling, this leads to the scm oom.
   
   @symious can you help reviewing this pr？
