ambari + Number of virtual cores level

subject - Number of virtual cores level not update after adding Vcore on data-node machines

we have data-node machines with 16Vcore in out hadoop cluster

we add another 16Vcore on each datanode machine ( worker machine ) , in order to get 32Vcore on each data-node

after that we restart the ambari-agent on each data-node machine , and validate the datanode host from ambari gui that set to 32Vcore ) and inded is set to 32Vcore,

but when we go to YARN --> CONFIG --> Number of virtual cores ( yarn.nodemanager.resource.cpu-vcores )



we see the "Number of virtual cores" level is still on 16Vcore instead 32Vcore

WHY?

example

CPU

Number of virtual cores

|-------------------------------|

.................................16Vcore

instead to get

CPU

Number of virtual cores

|---------------------------------------------------|

......................................................32Vcore
