That way, older installations and apps can continue to use the old APIs, and the new APIs do not need to take the unknown burden of making the old APIs work on the newer framework. This sounds a more reasonable commitment for ATS v2. > Compatibility doc to state that ATS v1 is a stable REST API > ----------------------------------------------------------- > > Key: YARN-3539 > URL: https://issues.apache.org/jira/browse/YARN-3539 > Project: Hadoop YARN > Issue Type: Improvement > Components: documentation > Affects Versions: 2.7.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Attachments: HADOOP-11826-001.patch, HADOOP-11826-002.patch, YARN-3539-003.patch, YARN-3539-004.patch > > > The ATS v2 discussion and YARN-2423 have raised the question: "how stable are the ATSv1 APIs"? > The existing compatibility document actually states that the History Server is [a stable REST API|http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#REST_APIs], which effectively means that ATSv1 has already been declared as a stable API. > Clarify this by patching the compatibility document appropriately -- This message was sent by Atlassian JIRA (v6.3.4#6332)
