The "Hive/HBaseIntegration" page has been changed by JohnSichi. http://wiki.apache.org/hadoop/Hive/HBaseIntegration?action=3Ddiff&rev1=3D17= &rev2=3D18 -------------------------------------------------- = * 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 key * 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 que= ries 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 =20
