------------------------------------
Summary: Kubernetes deployment does not respect
"taskmanager.cpu.cores".
Key: FLINK-16111
URL: https://issues.apache.org/jira/browse/FLINK-16111
Project: Flink
Issue Type: Bug
Components: Deployment / Kubernetes
Affects Versions: 1.10.0
Reporter: Xintong Song
Fix For: 1.10.1, 1.11.0
The Kubernetes deployment uses `kubernetes.taskmanager.cpu` for configuring TM
cpu cores, and will fallback to number-of-slots if not specified.
FLINK-14188 introduced a common option `taskmanager.cpu.cores` (ATM not exposed
to users and for internal usage only). A common logic is to decide the TM cpu
cores following the fallback order of "common option -> K8s/Yarn/Mesos specific
option -> numberOfSlot".
The above fallback rules are not respected by the Kubernetes deployment.
