On behalf of the Impala team at Cloudera, I am happy to announce the beta
release of Cloudera Impala, the industry’s first real time query framework
for Hadoop.

Impala is an open source real-time query engine that allows users to query
data stored in HDFS and HBase via a SQL interface. It leverages the same
metadata, SQL syntax (HiveQL), ODBC driver and Hue user interface (Beeswax)
as Apache Hive to provide a unified platform. But rather than using batch
processing MapReduce framework, Impala directly accesses the data locally
through a distributed query engine architecture. The result is an order of
magnitude performance improvement over Apache Hive depending on the type of
query. For more details on Impala, please see:

As part of the open beta, we encourage the CDH community to try it out.
Here is how you can get started:

- Access the download of Impala from
https://ccp.cloudera.com/display/SUPPORT/Downloads, install Impala and

RHEL/CentOS 6.2. We highly encourage the use of Cloudera Manager 4.1 to
deploy and manage Impala.
