Apache Impala SQL Overview
Use Apache Impala SQL to manage and access data in Hadoop storage.
Impala provides a high degree of compatibility with the Hive Query
Language. Impala uses the same metadata store as Hive to record
information about table structure and properties. Therefore, Impala can
access tables defined through the native Impala
TABLE command, or tables created using the Hive data
definition language (DDL).
