----------------------------------------
Summary: Master starts despite IllegalConfigurationException
Key: FLINK-18152
URL:
https://issues.apache.org/jira/browse/FLINK-18152 Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.11.0
Reporter: Chesnay Schepler
When no memory configuration parameters are set for the Master process then this exception is logged by the BashJavaUtils:
{code}
Exception in thread "main" org.apache.flink.configuration.IllegalConfigurationException: Either required fine-grained memory (jobmanager.memory.heap.size), or Total Flink Memory size (Key: 'jobmanager.memory.flink.size' , default: null $ at org.apache.flink.runtime.util.config.memory.ProcessMemoryUtils.failBecauseRequiredOptionsNotConfigured(ProcessMemoryUtils.java:111) at org.apache.flink.runtime.util.config.memory.ProcessMemoryUtils.memoryProcessSpecFromConfig(ProcessMemoryUtils.java:81) at org.apache.flink.runtime.jobmanager.JobManagerProcessUtils.processSpecFromConfig(JobManagerProcessUtils.java:76) at org.apache.flink.runtime.jobmanager.JobManagerProcessUtils.processSpecFromConfigWithNewOptionToInterpretLegacyHeap(JobManagerProcessUtils.java:71) at org.apache.flink.runtime.util.bash.BashJavaUtils.getJmResourceParams(BashJavaUtils.java:92) at org.apache.flink.runtime.util.bash.BashJavaUtils.runCommand(BashJavaUtils.java:66) at org.apache.flink.runtime.util.bash.BashJavaUtils.main(BashJavaUtils.java:54)
{code}
Afterwards, the Master process however continues to start just fine.
TaskManagers will not be started given the same situation, which is inconsistent behavior, and it seems dangerous to start a process despite an illegal configuration.
