Generally we only apply patches to trunk. Thus maintaining branches
becomes to much trouble for us. You have to remember that most hive
major versions have no actual major changes. Most everything is hidden
behind a query language. The only changes that have to be done
carefully are changes to the metastore that add things like views or
As for HIVE-2910, again this change made no changes to any core code.
HWI tries hard not to touch internals. As result I am almost 100%
positive you can replace hive-hwi-0.9.0.war with hive-hwi-0.10.0.war
in your hive lib directory, so you really do not need to wait for a
release just to get the new HWI.
As for improving HWI, hwi is a funny story. The open source hive had
no web interface, at the time the type of users that were into hive
and hadoop (since it was so new) where hardcore coders and distributed
systems experts. Those types do not typically use web interfaces. Fast
forward to now and EVERYONE and their grandmother uses hadoop and
suddenly web interfaces are actually an important selling point!
(I wrote hwi btw) In hive I have moved onto writing UDFs,
StorageHandlers, InputFormats, and doing patch reviews. The web
interface is low hanging fruit. If anyone wants to add a feature to
HWI (like the bootstrap one or others), open a jira and I will
promptly review and commit. Much like the features in the CLI
(autocomplete and .hiverc) they did not get better magically, but they
are again easy low hanging fruit that almost any coded can take care
