Karthik Kambatla commented on HADOOP-9517: ------------------------------------------ Thanks Steve. Will include all those items in the next version of the patch: # Source code compatibility - when you say the patch will apply (patch -p0), I suppose you are talking about the directory structure of the code and not that the patch will apply cleanly. From a contributor's perspective, this limits any directory changes include any code refactoring - e.g. move an inner class to a separate class. In that case, do we guarantee compatibility within a minor release or a major release. # Configuration: We already have the section - I ll add a note on the default values. # Will add user-level file formats, web UI # Will capture OS, JVM and Hardware under a new section Requirements. > Define Hadoop Compatibility > --------------------------- > > Key: HADOOP-9517 > URL: https://issues.apache.org/jira/browse/HADOOP-9517 > Project: Hadoop Common > Issue Type: Bug > Components: documentation > Reporter: Arun C Murthy > Assignee: Karthik Kambatla > Attachments: hadoop-9517.patch, hadoop-9517.patch, hadoop-9517.patch, > hadoop-9517.patch > > > As we get ready to call hadoop-2 stable we need to better define 'Hadoop > Compatibility'. > http://wiki.apache.org/hadoop/Compatibility is a start, let's document > requirements clearly and completely. -- This message is automatically generated by JIRA.
