The HCatalog team is happy to announce the release of HCatalog 0.4.0
Apache HCatalog provides a table management service for Hadoop. More details
about HCatalog can be found at http://incubator.apache.org/hcatalog
The highlights of this release are:
- Full support for reading from and writing to Hive.
- Support for deeply nested maps, arrays, and structs.
- Switch from StorageDrivers to SerDes. HCatalog no longer supports its own
StorageDriver classes for data (de)serialization. Instead it uses Hive's SerDe
classes.
- Addition of JSonSerDe to support reading and writing JSON data.
- The HCatalog binary distribution no longer includes Apache Hive. We now
require that Hive first be installed.
- The HCatalog source distribution no longer includes Apache Hive source. It
now pulls the required jars via maven.
