Subject [Hadoop Wiki] Update of "Hive/HBaseIntegration" by JohnSichi
Date Wed, 10 Mar 2010 00:58:42 GMT
Dear Wiki user,

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

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


   * more flexible column mapping (HIVE-806)
   * default column mapping in cases where no mapping spec is given
-  * filter/projection pushdown
+  * filter pushdown
   * expose timestamp attribute, possibly also with support for treating it as a partition
   * allow per-table hbase.master configuration
   * run profiler and minimize any per-row overhead in column mapping
   * user defined routines for lookups and data loads via HBase client API (HIVE-758 and HIVE-791)
-  * support a fast-path mode in which no map/reduce is used for simple queries and loads
(go through HBase client API instead)
   * logging is very noisy, with a lot of spurious exceptions; investigate these and either
fix their cause or squelch them
   * replace dependencies on deprecated HBase API's such as RowResult
