Subject Each yarn container only use 1 vcore even if taskmanager.numberOfTaskSlots is set
Date Mon, 18 Feb 2019 02:49:24 GMT
Hi Experts,
	I am running Flink 1.7.1 program on Yarn 2.7, the taskmanager.numberOfTaskSlots is set to
4. The parallelism.default is set to 8. When the program is running, 3 yarn containers is
launched, but each of them only use 1 vcore, I think by default the number of vcores is set
to the number of slots per TaskManager.
	Because it can not get enough CPU resources, the CPU load may be high. So how can this problem
be fixed? 
	Thanks a lot for your help.
