Lefty Leverenz commented on HIVE-15622:
---------------------------------------

A few HWI complaints have been voiced since 2012:

* [user@hive "Release 1.2.1 missing hwi-war file" | 
http://mail-archives.apache.org/mod_mbox/hive-user/201602.mbox/%3ccab0we8bc9qovpt2htfjutsznqxgig4b2keaksvy8j5pt2at...@mail.gmail.com%3e]
** [Same issue is in latest hive version 2.0.0. | 
http://mail-archives.apache.org/mod_mbox/hive-user/201602.mbox/%3cCAB0WE8Z=VvJuA=jte-1ozvmgfmy627mi4sfuaoazdzncloo...@mail.gmail.com%3e]
* duplicates:
** HIVE-8214 Release 0.13.1 missing hwi-war file
** HIVE-7380 HWI war is not packaged in tar.gz
** HIVE-7233 File hive-hwi-0.13.1 not found on lib folder
* HIVE-5132 Can't access to hwi due to "No Java compiler available"

By the way, if you remove HWI then its wikidoc needs a version note (but should 
not be deleted) and three HWI configuration parameters need updates:

* [Hive Web Interface | 
https://cwiki.apache.org/confluence/display/Hive/HiveWebInterface]
* [Configuration Properties -- Hive Web Interface (HWI) | 
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-HiveWebInterface(HWI)]

> This component seems to be obsolete, as it didn't get any meaningful update 
> since 2012. And we don't see people discussing or complaining issues about 
> this. Moreover, it caused a number of ptest issues which can be avoided.
> We should remove this component as a cleanup effort.
