-----------------------------------
yes, as current node label will divide the current cluster into several
sub-clusters. If Constrain Label feature ready, it will help on this. So it is
a temporary solution to solve the current situation. Welcome to update this.

> Support multi-label merge into one node label
> 1. we want to support multo-label like SSD,GPU,FPGA label merged into single
> machine, joined by &. like SSD,GPU,FPGA-> SSD&GPU&FPGA
> 2. we add wildcard match to extend the job request. we define the wildcard
> like *GPU*, it will math all the node labels with GPU as part of multi-label
> merged label. For example, *GPU* will match SSD&GPU&FPGA, GPU&FPGA. We
> define SSD&GPU&FPGA={SSD,GPU,FPGA}, and GPU is one of {SSD,GPU,FPGA}, so the
> job can run on SSD&GPU&FPGA node.
