These CPU intensive processes run inside the container:

  • Postgres
  • Teradata Aster SQL-MapReduce™ and Teradata Aster SQL-GR™ jobs

The formula for the total number of vWorkers per Aster-YARN container (according to CPU) is:

Xc = ((Max container CPU limit) - 1)/4

The number 4 in the above equation represents the number of CPU cores that are requested for one Aster vWorker on YARN.
