Subject [jira] Commented: (HIVE-144) Ql java source copied to build/gen-java

Joydeep Sen Sarma commented on HIVE-144:
----------------------------------------

I would really like to see Hive be available for multiple versions of Hadoop.  As a company
we are using Hadoop-17 - and i know of many other companies that don't keep up with latest
releases of Hadoop (typically - once they have things working well on a particular version
of hadoop - they tend to be conservative with hadoop upgrades).

the difference is that Hive is relatively immature and fast moving software right now where
people are willing/wanting to try out the latest version (even while they continue using older
version of Hadoop). So having latest features from Hive be available on older releases will
really help in adoption.

> Since HIVE-98, the build process copies the contents of the ql/src/java directory to
build/gen-java where the code generated from Hive.g is located. This makes it a bit more difficult
to work on the project in Eclipse, since one has to add the build/gen-java folder to the project
and not ql/src/java. This means we'll edit the ql java files in the wrong location. Adding
both of these directories will of course result in duplicate entries.
