Please vote (binding or unbinding) on the following proposal. The vote will be open until 3pm (Pacific) April 13th.
Proposal: Move master to support minimum Hadoop 3+ (0.10.x line) and create separate branch for Hadoop 2 (0.9.x line) Details: - Tez master branch would support only Hadoop 3+ moving forward - As a general policy, Maven dependencies on master are required not to have conflicts with the dependencies of the corresponding minimum supported Hadoop (the dependency versions can vary between Tez master and Hadoop if the versions are advertised as compatible by the dependency provider). - As a general policy, dependency conflicts between Tez and Hadoop should be resolved by using compatible jars. Shims/Shading could be used on a case-by-case basis, but not as a general policy. - A separate branch and distribution (e.g. on Maven Central) will be created to maintain the 0.9.x line with minumum support for Hadoop 2.7.x - Bug fixes would be required to be pushed to both to master and the 0.9.x line (unless they are specific to one of them) - Major feature or performance improvements would be required to be pushed to both master and the 0.9.x line (unless they require Hadoop 3+ or have dependent library conflicts with Hadoop 2.x, in which case they may be pushed only to master) - Minor feature or performance improvements can be pushed only to master
