----------------------------------------
Summary: Jobstore size check compares against offHeapMemory
Key: FLINK-18157
URL: https://issues.apache.org/jira/browse/FLINK-18157
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.11.0
Reporter: Chesnay Schepler
Setting {{jobmanager.memory.off-heap.size}} to 0 results in this confusing
error:
{code}
[] - Loading configuration property: jobmanager.memory.process.size, 2000m
[] - Loading configuration property: jobmanager.memory.heap.size, 1500m
[] - Loading configuration property: jobmanager.memory.jvm-overhead.min, 100m
[] - Loading configuration property: jobmanager.memory.jvm-overhead.max, 350m
[] - Loading configuration property: jobmanager.memory.off-heap.size, 0m
[] - The configured or derived JVM heap memory size (jobstore.cache-size: 0
bytes) is less than the configured or default size of the job store cache
(jobmanager.memory.heap.size: 50.000mb (52428800 bytes))
{code}
According to the documentation the jobstore uses the heap though.
{code}
private static JobManagerFlinkMemory createJobManagerFlinkMemory(
Configuration config,
MemorySize jvmHeap,
MemorySize offHeapMemory) {
verifyJvmHeapSize(jvmHeap);
verifyJobStoreCacheSize(config, offHeapMemory);
return new JobManagerFlinkMemory(jvmHeap, offHeapMemory);
}
private static void verifyJvmHeapSize(MemorySize jvmHeapSize) {
if (jvmHeapSize.compareTo(JobManagerOptions.MIN_JVM_HEAP_SIZE) < 1) {
LOG.warn(
"The configured or derived JVM heap memory size ({}) is
less than its recommended minimum value ({})",
jvmHeapSize.toHumanReadableString(),
JobManagerOptions.MIN_JVM_HEAP_SIZE);
}
}
{code}
