Hive provides SQL-like query language on HDFS(Hadoop Distributed File System)

Hive defines a simple SQL-like query language, called QL, that enables users familiar with SQL to query the data. At the same time, this language also allows programmers who are familiar with the MapReduce framework to be able to plug in their custom mappers and reducers to perform more sophisticated analysis that may not be supported by the built-in capabilities of the language. QL can also be extended with custom scalar functions (UDF's), aggregations (UDAF's), and table functions (UDTF's). Hive Query Lan...

Apache HBase is a storage system, with roots in Hadoop, and uses HDFS for underlying storage.

Apache HBase is a storage system, with roots in Hadoop, and uses HDFS for underlying storage.Apache HBase is a storage system, with roots in Hadoop, from which it gets its "H". Though HBase uses HDFS for underlying storage, HBase is designed much more for fast and frequent access to blobs of binary data. It is an example of what most would call a NoSQL column-oriented store; it holds semi-structured values for keys. Below is the reference architecture based on HDFS, MapReduce, and HBase. MapReduce might be used for parallel processing to calculate something. I will search much detailed knowledge in...
