I don't know enough about Hive/Hadoop to provide a definitive
answer, but in general Liquibase is extensible to new database types. In
version 3.x there is still some database-specific code in Liquibase
core, but I know that Nathan (the guy who wrote Liquibase and still the
project owner) is planning to remove that in the 4.0 version, which is
currently in the early stages.
There are some docs on writing your own extensions, as well as
information on the extensions currently available at https://liquibase.jira.com/wiki/display/CONTRIB/LiquiBase+Extensions+Portal
