Description

Starting jobmanager pod should respect containerized.heap-cutoff. The cutoff will be used to leave some memory for jvm off-heap, for example meta space, thread native memory and etc.

 

public static final ConfigOption<Float> CONTAINERIZED_HEAP_CUTOFF_RATIO = ConfigOptions
 .key("containerized.heap-cutoff-ratio")
 .defaultValue(0.25f)
 .withDeprecatedKeys("yarn.heap-cutoff-ratio")
 .withDescription("Percentage of heap space to remove from containers (YARN / Mesos / Kubernetes), to compensate" +
  " for other JVM memory usage.");
