Xuze Yang updated YARN-11603:
-----------------------------
Description:
See the following scenarios:
{*}Total cluster resources{*}:<memory: 13312, vCores: 4, yarn. io/gpu: 2>
{*}Queue{*}:
root
-default (50%)
-autotest (50%)
{*}Task{*}: mapreduce task, 1 am, 1 map, 1 reduce
{*}Task1{*}: Do not request for GPU
{*}Task2{*}: Request for 2 gpu in the map
{*}Test scenario and results{*}: Firstly, using hadoop user to submit Task2 to
the default queue, which can be allocated to resources normally. Afterwards,
using hadoop user to submit Task1 to the default queue, which cannot allocate
resources.
I think in this situation, Task1 should also be allocated to resources and run
normally.
