Compute Unit (ECU ), an ECU represents the processing capacity equivalent to 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processors. YARN proposes the Minimum CPU Unit YARN Compute Unit (YCU). Currently, this number is an integer. The default value is 720. nodemanager. resource. cpu-ycus-per-core indicates the computing power of a CPU core (this feature does not exist in version 2.2.0 and may be added to version 2.3.0, when submitting a job, you can directly specify the required YCU.
