Using the HBase-Spark connector
You can use HBase-Spark connector on your secure cluster to perform READ and WRITE operations. The HBase-Spark Connector bridges the gap between the simple HBase Key Value store and complex relational SQL queries and enables users to perform complex data analytics on top of HBase using Spark.
An HBase DataFrame is a standard Spark DataFrame, and is able to interact with any other data sources such as Hive, ORC, Parquet, or JSON.
