Description

IMPALA-9791 added support in catalog to return the table metadata which consistent with respect to a given ValidWriteIdList. In theory it is possible that this can give false positive (table is consistent with respect to the provided ValidWriteList but in reality its not). This can happen when the table is dropped and recreated with same name without the knowledge of catalog. We should compare the ValidWriteIdList only when the cached table's id matches with the tableId as provided by the client or from HMS.
