    Description

      In the case that the impalad has cached some information about a table, but the table has since been modified or deleted on the catalogd, the metaprovider can throw an InconsistentMetadataException after invalidating the cached information. On a re-plan, we'll see the new version and avoid the issue. The front-end needs to catch the exception and trigger the replan.
