Subject [Hadoop Wiki] Update of "Hive/StorageHandlers" by JohnSichi
Date Tue, 09 Mar 2010 23:43:46 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hive/StorageHandlers" page has been changed by JohnSichi.


   * FileSinkOperator should probably be refactored, since non-native tables aren't accessed
as files, meaning a lot of the logic is irrelevant for them
   * It may be a good idea to support temporary disablement of metastore hooks as part of
manual catalog repair operations
   * The CREATE TABLE grammar isn't quite as strict as the one given above; some changes are
needed in order to prevent STORED BY and row_format both being specified at once
+  * CREATE TABLE AS SELECT is currently prohibited for creating a non-native table.  It should
be possible to support this, although it may not make sense for all storage handlers.  For
example, for HBase, it won't make sense until the storage handler is capable of automatically
filling in column mappings.
