-------------------------------------------------------------
*the third time, version:2.6.0*
This time it happened when the NM restarted, and the container needs to be
recover after the NM restart. After analysis, it is suspected that it may be
stuck in the check of isContainerAlive() in
ContainerExector.reacquireContainer(), where a kill -0 $ pid command was
executed, I use DefaultContainerExecutor.
