Hive development !

With Hive you can
  • do ETL and analysis using QL (a SQL like query language)
  • create table with partition or bucketed table !
  • compress your data !
  • use java reflection to instantiate and call methods of objects
  • build custom scalar functions (UDF's), aggregations (UDAF's), and table functions (UDTF's)
