Subject [jira] [Commented] (YARN-5606) Support multi-label merge into one node label
Date Wed, 07 Sep 2016 08:45:20 GMT

jialei weng commented on YARN-5606:
-----------------------------------

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.
