Hi Big Data Explorers,
The Hue Team is glad to thanks all the contributors and release Hue 4.4! [
][1]
The focus of this release was to improve the self service SQL troubleshooting and stability.
This release comes with 450 commits and 80+ bug fixes! For all the changes, check out the [release notes][2].
Go grab the tarball or [source][3], and give it a spin! And for a quick try, 'docker pull gethue/4.4.0' or open-up [demo.gethue.com][4].

And what it looks like now:

Note that on top of the much simpler visualization, tips are provided when available:

][10]
Please read more about this feature in this [complete self-troubleshooting scenario][11].
Additionally, one of the most requested fixes was implemented: releasing query resources after the query has finished and they are no longer needed.
First, on the [Apache Impala][12] side, the query execution status will properly say if the query is actively running ("processing" data) or just "open but finished" (meaning just "keeping" the results but not using resources).
In addition, the new parameter NUM_ROWS_PRODUCED_LIMIT will even notify Impala to truncate any query execution as soon as this maximum number of result rows has been returned. This will release resources early on large SELECT operations where only the first few rows are actually displayed (which is the primary use case in Hue).
## Better compatibility with Hive in HDP
Apache Hive has typically been very innovative in the Hortonworks distribution. In upstream the support for Hive on Tez and Hive LLAP was improved. Now:

Last but not least, the [upstream][18] and [downstream][19] documentation just got the first pass of a revamp, with a better table of contents, restyling, and updated instructions. In particular, on the upstream docs, reporting issues or sending a suggestion is one click away via GitHub, so feel free to send some pull requests!
Thank you to everybody using the product and who contributed to this release. Now off to the next one!
As usual thank you to all the project contributors and for sending feedback and participating on the [hue-user][20] list or [@gethue][21]!
Onwards!
