Subject Re: when to use hive vs hbase
Date Wed, 30 Apr 2014 10:31:40 GMT
HDFS lacks random read and write accees. This is where HBase comes into
picture.It stores data as key/value pairs.
Hive provides  data warehousing facilities on top of an existing Hadoop
cluster. It provides an SQL like interface which makes your work easier.
You can create tables in Hive and store data there. Along with that you can
even map your existing HBase tables to Hive and operate on them.
