Summary: Support multi-label merge into one node label
Key: YARN-5606
URL: https://issues.apache.org/jira/browse/YARN-5606
Project: Hadoop YARN
Issue Type: New Feature
Reporter: jialei weng
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.
