Hitesh Shah created TEZ-3168: -------------------------------- Summary: Provide a more predictable approach for total resource guidance for wave/split calculation Key: TEZ-3168 URL: https://issues.apache.org/jira/browse/TEZ-3168 Project: Apache Tez Issue Type: Bug Reporter: Hitesh Shah Assignee: Hitesh Shah
Currently, Tez uses headroom for checking total available resources. This is flaky as it ends up causing the split count to be determined by a point in time lookup at what is available in the cluster. A better approach would be either the queue size or even cluster size to get a more predictable count. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
