Hi, I have a question on the consistency between data (e.g., on HDFS) and metadata kept by Metastore before and after compaction.
Here is a scenario: 1. We back up the database for Metastore (before performing compaction). 2. We perform compaction. 3. After performing compaction, we lose the database for Metastore by accident. The question is: can we restore and use the backup database for Metastore along with the data after compaction? As incremental changes/deltas are stored on data storage, I guess this might be feasible, but not sure. Any comment would be appreciated. Thanks, --- Sungwoo
