----------------------------------
Summary: FineGrainedSlotManager may not allocate enough
taskmangers if maxSlotNum is configured
Key: FLINK-32254
URL: https://issues.apache.org/jira/browse/FLINK-32254
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.18.0
Reporter: Weijie Guo
Assignee: Weijie Guo
We ran a job with {{slotmanager.number-of-slots.max = 10}},
{{taskmanager.numberOfTaskSlots = 10}} and {{taskmanager.memory.process.size:
24000m}}. The resources of the cluster are sufficient, but no TaskManager can
be allocated. It seems that there is a problem with the calculation logic of
{{SlotManagerConfiguration#getMaxTotalMem}}. Due to the rounding down of
division, the calculated {{MemorySize}} is too small.
