Re : Support for Hive (Hadoop) schema changes via Liquibase?

Hi,

I've been trying to understand the codebase for sometime to see whether it is possible to make use of liquibase to handle schema changes for Impala/Hive. At first glance, come to know that CRUD operations are happening on two important tables - 1. databasechangeloglock 2. databasechangelog as it is heavily used to persist the state. 

Hive/Impala doesn't have ACID support - No Transactional support, No CRUD support in my distribution although there is support (but not as full fledged feature) in general community version. Thought of sharing this info and asking for your suggestions. Thoughts? Is anyone trying out this?

Is it possible to keep these core tables somewhere outside in RDBMS (for ex, mysql) as common place for all Hive/Impala databases? Yes, there could be problems in maintain the integrity between these two operations.

Thanks,
Mani
