Subject [ANNOUNCE] HCatalog 0.4.0 released
Date Thu, 17 May 2012 23:36:28 GMT
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

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.
