Impala is an open-source product for parallel processing (MPP) SQL query engine for data stored in a local system cluster running on Apache Hadoop. Almost all Database vendors are using the JDBC connector available specific for the typical Database; Sqoop needs a JDBC driver of the database for further interaction. Impala runs and gives us output in real-time. This article describes how to connect to and query Impala data from an Apache NiFi Flow. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.
