Xuze Yang created YARN-11603:
--------------------------------
Summary: Resourcemanager cannot allocate resources to tasks when a
dimension's resources are used up
Key: YARN-11603
URL: https://issues.apache.org/jira/browse/YARN-11603
Project: Hadoop YARN
Issue Type: Bug
Components: yarn
Reporter: Xuze Yang
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 can
allocate resources normally. Afterwards, using hadoop user to submit task1
cannot allocate resources
I think in this situation, Task1 should also be allocated to resources and run
normally.
