USING LIGHTWEIGHT JIT COMPILATION FOR SHORT-LIVED JVMS ON PARALLEL DISTRIBUTING COMPUTING FRAMEWORK

摘要

A computer-implemented method and computer program product are provided for restarting a virtual machine for processing each of a plurality of jobs in a parallel distributed computing framework. The method includes estimating whether or not the virtual machine is short-lived, by using multiple criteria obtainable from metadata. The multiple criteria includes a number of workload columns, a number of workload splits, and a size of data types corresponding to the virtual machine. The method further includes restarting the virtual machine with a configuration of using only a lightweight Just In Time compilation by specifying its virtual machine argument, responsive to the virtual machine being estimated as short-lived.
