Hadoop is a collection of open source products and technologies administered by the Apache Software Foundation. CDH is Cloudera’s Hadoop distribution. Cloudera Impala is an integrated part of CDH that provides an analytic database.
Cloudera Impala adds a real time query capability that shares the metadata layer and query language with Hive. It is available on CDH and other selected Hadoop distributions.
The Cloudera Impala adapter is JDBC based. The DataMigrator or WebFOCUS server can be run on any platform (including Windows) that connects to the server where Cloudera Impala is running.
Cloudera Impala can be accessed with either the Apache Hive JDBC driver or the Cloudera Impala JDBC driver.
