Ryan, This is hard to say. There are many changes going in around indexing and authorization. IMHO everyone is taking a lot of care in the design however, it is still subject to change. If i were compelled to update I would spin up a new instance into a new meta-store back end. Then compare the schema of current with 0.6.X like a diff of 'show create tables'. Just an FYI. I applied two different hive trunks between 0.5 and 0.6. and I never needed the update scripts because hive happily updated the schema for me. After my final upgrade to 0.7.0 I re-ran everything in the upgrade script just to be safe. Nothing noticeably bad happened to me during the duration. I suspect many people will not need to run the update scripts since in the stock configuration hive seems to auto-update anyway. (Someone correct me if I am wrong here.) Does anyone know how to specifically which variable controls this? Edward
