Apache beehive is mainly Second hand for batch processing ie OLAP but HBase is extensive Second hand for transaction processing, with the answer time of inquiry is not very interactive, ie OLTP. not how beehive, operations are performed in HBase realtime on the database instead of turning them into MapReduce jobs.

What is Hadoop technology for?

Hadoop is an open source software framework for storing data and running applications on clusters of commodity hardware. It offers massive storage space for any type of data, tremendous processing power, and the ability to handle virtually unlimited concurrent tasks or jobs.

What is Hbase and Hive?

PIG used for data transformation tasks. You have a file, you want to extract useful information from it, or you want to join two files together, or use another transformation PIG. BEEHIVE used to query these files by defining a “virtual” table and running SQL-like queries against these tables. HBase is a full-fledged NoSQL database.

What is the difference between impala and beehive?

Apache beehive may not be ideal for interactive computing, while impala is intended for interactive computing. beehive is batch-based Hadoop MapReduce while impala is more like an MPP database. beehive supports complex types though impala not. Apache beehive is fault tolerant while impala does not support fault tolerance.

What is a beehive?
