The Apache Tez team is proud to announce the release of Apache Tez version 0.5.0.
The Apache Tez project is aimed at creating a framework to build efficient and scalable data processing applications that can be modelled as data flow graphs. Tez 0.5.0 is a developer focused release that stabilizes the APIs and improves the debugging experience for Tez applications. The following items outline the important features of this release 1) Stable APIs - The core DAG and Runtime APIs have been marked stable and will be compatibly supported going forward. So developers can take a dependency on these APIs. The convention is that classes, methods configuration that have been explicitly annotated as @Public and @Stable are going to be compatible. Classes, methods and configurations that have been marked @Evolving and @Unstable may continue to change going forward. Classes, methods and configurations that have been marked @Private are not to be used. 2) Documentation - This release produced the first javadocs for Tez and a number of tutorial like examples have been added to learn the APIs 3) Local mode execution - Tez applications can be run without running a cluster. This mode is to be used for debugging the application locally. 4) Performance debugging tools - New tools like swimlanes analysis have been added to help in debugging the performance of Tez applications 5) Support for ACLs - Tez now supports ACLs for fine grained access control to view and modify DAGs. 6) New intermediate data format - Initial support for a new data format for intermediate Key Value data for better performance. 7) Added UnorderedPartitionedOutput - This new output was added to write key value data into partitions with the data being unordered in these partitions. In addition there have been a number of performance and stability improvements made. For full details please look at CHANGES.txt in the release artifacts. There are a number of incompatible changes in this release. For a full list, please look at CHANGES.txt in the release artifacts.
