-------------------------------------------
Summary: AM Web service V2: Make dagInfo & verticesInfo APIs
accept dagMinID as query param
Key: TEZ-2793
URL: https://issues.apache.org/jira/browse/TEZ-2793
Project: Apache Tez
Issue Type: Sub-task
Reporter: Sreenath Somarajapuram
- Currently we are expecting dag index on a query param with name dagID, which
is counter intuitive.
- The concept of MinID was brought in to minimize the url size.
-- They are minimized version of complete entity ID.
-- dagMinID = dagIndex
-- vertexMinID = vertexIndex
-- taskMinID = vertexIndex_taskIndex
-- attemptMinID = vertexIndex_taskIndex_attemptNo (vertexIndex_taskIndex =
vertexIndex_taskIndex_0 making it shorter in most cases)
--- For instance. A complete attempt id looks like
attempt_1441301219877_0111_1_02_000049_0. The same can be referenced under a
DAG with a minimized version 2_49_0.
- Looks meaningful to accept all query params as min-ids from API v2.
