Subject [jira] [Created] (HIVE-10420) Black-list for table-properties in replicated-tables.
Date Tue, 21 Apr 2015 17:37:00 GMT
Mithun Radhakrishnan created HIVE-10420:

             Summary: Black-list for table-properties in replicated-tables.
                 Key: HIVE-10420
             Project: Hive
          Issue Type: Bug
          Components: HCatalog, Metastore
            Reporter: Mithun Radhakrishnan
            Assignee: Mithun Radhakrishnan

(Not essential for 1.2 release, although this'll be good to have.)
When table-schema changes are propagated between 2 HiveMetastore/HCatalog instances (using
{{HCatTable.diff()}} and {{HCatTable.resolve()}}, some table properties are replicated identically,
even though those properties might be specific to the source-table (or source-metastore).

For instance,
# Last update/DDL time
# JMS message coordinates
# Whether or not the table is external (ideally)

We should run the replication properties through a black-list filter, and have these removed
when generating diffs, or replicating tables.
