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

--------------------------------------------------

  
  = Open Issues =
  
-  * The storage handler class name is currently saved to the metastore via 
table property {{{storage_handler}}}; this should probably be a first-class 
attribute on MTable instead
+  * The storage handler class name is currently saved to the metastore via 
table property {{{storage_handler}}}; this should probably be a first-class 
attribute on MStorageDescriptor instead
   * Names of helper classes such as input format and output format are saved 
into the metastore based on what the storage handler returns during CREATE 
TABLE; it would be better to leave these null in case they are changed later as 
part of a handler upgrade
   * A dummy location is currently set for a non-native table (the same as if 
it were a native table), even though no Hive files are created for it.  We 
would prefer to store null, but first we need to fix the way data source 
information is passed to input formats (HIVE-1133)
   * Storage handlers are currently set only at the table level.  We may want 
to allow them to be specified per partition, including support for a table 
spanning different storage handlers.
