- v0.4.0, released March 31, 2010.
- Cloudera Desktop 0.4.0 is a significant update from the previous version 0.3.0.
- This release introduces the Cloudera Desktop SDK, a way to plug in your own
- applications that leverage the Cloudera Desktop environment. Another new
- feature is Beeswax, a front-end application for interacting with Hive. It also
- represents many bug fixes and a re-working of the "Job Browser" and "File
- Browser" applications.
- NEW FEATURES
- - Beeswax, a UI for Hive
- Beeswax is an application for managing and using Hive. It allows users
- to create tables, load data, and query the warehouse, all from their
- browser.
- - The Cloudera Desktop SDK
- It is now possible to add your own applications into Cloudera Desktop,
- integrated with the windowing system and the other applications.
- To get started, see the SDK documentation.
- - File Editor
- It is now possible to edit (small, text) files directly from the File Browser.
- This is particularly handy for editing small configuration files.
- - "About" Application
- Reachable by clicking the Cloudera "feather" in the upper lefthand corner,
- the about application displays the current configuration.
- IMPROVEMENTS
- - File Browser
- The File Browser has been re-architected on top of the SDK.
- Changing permissions and changing file ownership is now possible.
- Performance on large directories is improved.
- - Job Browser
- The Job Browser has been re-architected on top of the SDK.
- There have been several performance improvements in handling
- large jobs.
- - Job Designer
- You may register for e-mail notifications when jobs you
- submit have completed.
- - Session Restore
- Windows that were open when you last logged out are
- opened again automatically when you log back in.
- - Support for privileged ports and SSL.
- You can now run Desktop on port 80, and, optionally, with SSL (see the FAQ).
- - Cleaner SDK Model for "JFrame"
- Most requests within Cloudera Desktop are now, under the covers,
- simple GET and POST requests which return HTML.
- - SDK-Friendly Build System
- The build system has been adapted to support third-party applications
- and dependencies gracefully.
- - Users can now change their own passwords.
- - Keyboard Shortcuts
- A list of available shortcuts is available in the top right corner (click the
- "command" icon).
- - Usage without Hadoop
- Cloudera Desktop will run if Hadoop is unavailable, though
- some applications will be limited in functionality.
- - Frontend Javascript Performance and Compatibility
- Many improvements in windowing performance.
- KEY BUG FIXES
- - Creating a "home directory" while creating the user in the user manager
- no longer produces an error.
- - Dates and times are now displayed in a specific timezone, which is configurable.
- - Inactive users are not able to login.
- - The Job Designer appropriately configures hadoop.tmp.dir; this fixes
- some permissions denied errors.
- - File upload is more robust.
- KNOWN BUGS
- - After a successful upload with Linux's flash player (which may warn you about
- hanging your computer), the upload screen does not clear. Click the red
- (x) button to clear it.
- - Configuring the web server to listen on port 80 does not work if you are
- using the RPM or Debian packages. This is due to the init scripts
- improperly dropping root privileges before calling the supervisor. This
- has been fixed in release 0.4.1.
