while starting task manager, I got the error below {code:java} "Caused by: org.apache.flink.configuration.IllegalConfigurationException: The required configuration option Key: 'taskmanager.cpu.cores' , default: null (fallback keys: []) is not set {code} Checking TM starting command I got something like {code:java} -D taskmanager.memory.framework.off-heap.size=134217728b -D taskmanager.memory.network.max=67108864b -D taskmanager.memory.network.min=67108864b -D taskmanager.memory.framework.heap.size=134217728b -D taskmanager.memory.managed.size=57346620b -D taskmanager.cpu.cores=1.0 -D taskmanager.memory.task.heap.size=1518663108b -D taskmanager.memory.task.off-heap.size=0b {code} Looks like the extra spaces between "-D" and parameters causes those dynamic options can't be passed in correctly.
