Using Impala to query external JDBC data sources (Preview)

Apache Impala now supports reading from external JDBC data sources. An external JDBC table represents a table or a view in a remote RDBMS database or another Impala cluster. Using external JDBC tables, you can connect Impala to a database, such as MySQL, PostgreSQL, or another Impala cluster and read the data in the remote tables.
