Wei Yan updated YARN-2618: -------------------------- Attachment: YARN-2618-2.patch Thanks, [~kasha]. Update a new patch to fix the comments. The existing patch works well with FairScheduler. But for FifoScheduler and CapacityScheduler, it cannot avoid over-allocating disk resources. This is because both Fifo and Capacity only care memory capacity when assigning containers to nodes, and support over-consuming for cpu resources. [~jianhe], do u know any special reason why CapacityScheduler support over-consuming cpu resources? > 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 > > > 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)
