GOBBLIN 0.7.0

Created Date: 05/11/2016

Highlights

Gobblin has deprecated support for Hadoop 1.x.x - Gobblin will build with Hadoop 2.3.0 by default, and will throw an exception if users try to build against 1.x.x versions
Gobblin can now write data to Relational Databases via a new JDBCWriter; the Writer is capable of writing to any RDMS connectable via JDBC, however, our testing has focused on writing to MySQL
- Documentation: http://gobblin.readthedocs.io/en/latest/user-guide/Gobblin-JDBC-Writer/
Gobblin can now automatically register published datasets into Hive
- Documentation: http://gobblin.readthedocs.io/en/latest/user-guide/Hive-Registration/
Gobblin has a new adaptor that can do a distributed copy of data between Hadoop clusters (many improvements over Hadoop's Distcp Tool); it can also has upcoming support for replicating Hive tables between different Metastores
- Documentation: http://gobblin.readthedocs.io/en/latest/adaptors/Gobblin-Distcp/
Gobblin has a new configuration management system that is focused on configuring datasets in a reliable and sensible way; the system is largely based on Typesafe's Config library
- Documentation: http://gobblin.readthedocs.io/en/latest/adaptors/Gobblin-Distcp/

[Admin Dashboard] Added a CLI for finding jobs in the job history store and seeing their run details (thanks Eric Ogren).
[Configuration Management] WIP: Configuration management library. Will enable Gobblin to be dataset aware, ie. to dynamically load and apply different configurations to each dataset in a single Gobblin job. ** APIs: APIs for configuration stores and configuration client. ** Configuration Library: loads low level configurations from a configuration store, resolves configuration dependencies / imports, and performs value interpolation.
