Abstract

The invention discloses a data access method and a system, which are applied to a Spark, the Spark integrates an LLAP daemon. The method comprises the following steps of: receiving a data query statement; using the Apache Ranger LLAP plug-in, the access control rules stored in the Ranger being obtained; obtaining a data access plan corresponding to the data query statement by using the LLAP daemon; using the LLAP daemon, the data access plan being executed according to the access control rules. A Spark in the invention utilizes an integrated LLAP daemon to read data, and through Apache Rangerto LLAP daemon access rights control, Spark data fine-grained access rights control then can be achieved to protect the security of Spark data fine-grained access.

Description

technical field [0001] The present invention relates to the field of data query mining, and more specifically, to a data access method and system. Background technique [0002] Spark is a Hadoop-like MapReduce general-purpose parallel framework open sourced by UC Berkeley AMP lab (AMP Lab of the University of California, Berkeley), which plays a very important role in general-purpose distributed computing scenarios. [0003] Currently, Spark supports most of the mainstream programming languages ​​on the market, such as Python, Scala, Java and R languages. When Spark is used as a general computing framework, and when Java / Scala / Python is used to express logic services that cannot be encapsulated in SQL statements, it is more suitable to use Spark to execute data queries. However, Spark uses Kerberos for authentication and SSL for encryption. In this way, authorization operations can only be performed through HDFS ACL. When applied to a structured schema with columns and row...
