Hive and Hbase integration is not a good choice if you want to
perform anything in real time.Hive is suitable for batch processing.
Hive is a data warehouse that works on top of Hadoop and provides SQL
like functionality. When you fire a Hive query it first gets converted
into a MapReduce job (under the hood) and then provides the desired
And, as far as speed of execution is concerned, any Hadoop project
would be a good choice when we have to handle "large" data sets. We
cannot expect RDBMS kind of functionality when we are talking about
Hbase. But, once you are confident that Hive-Hbase integration fits
into your requirements then nothing could be a better choice.
You can have a look at the below specified links that show Java API usage -
(Operating on HBase columns throuh Java).
(Performing various operations on a Hbase table through Java).
Hive clients that include Thrift, JDBS, ODBC etc).

reduce in java).
speaks about Hive-Hbase integration).

> hey Dalia ,
