There's a section at the end on extending vdisks to include spindles but it wasn't clear on how to extend it. If the vdisks in the Resource class represents a share of disk operations, can we change the name in the Resource class as well to reflect this(from vdisks to something else)? > Avoid over-allocation of disk resources > --------------------------------------- > > Key: YARN-2618 > URL: https://issues.apache.org/jira/browse/YARN-2618 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Wei Yan > Assignee: Wei Yan > Attachments: YARN-2618-1.patch, YARN-2618-2.patch, YARN-2618-3.patch, YARN-2618-4.patch, YARN-2618-5.patch > > > Subtask of YARN-2139. > This should include > - Add API support for introducing disk I/O as the 3rd type resource. > - NM should report this information to the RM > - RM should consider this to avoid over-allocation -- This message was sent by Atlassian JIRA (v6.3.4#6332)
