Angel 2.2.0 Release

In this Release, we have enhanced the graph algorithms: (1) we made a refactoring of the existing K-Core algorithm, the performance and stability have been significantly improved; (2) we add louvain algorithm, which is also based on Spark On Angel. The test results show that the K-Core and Louvain based on Spark On Angel are 1~2 orders of magnitude faster than the original version of Spark. In this release we official release the Vero, the new GBDT implement based on the Spark On Angel, which has obvious advantages in supporting high dimensional models and multi-classification problems. We also add kerberos support in this release.
