      Description

      MetadataDataset uses an IndexedTable underneath. To upgrade this dataset (add new columns, re-index existing metadata, etc), currently CDAP runs the upgrade tool.

      However, this may result in downtime (for the upgrade to complete). There should be a way to perform this upgrade without having to run the upgrade tool (e.g. run it in the background after CDAP starts up).
