The invention provides an HBase table conjunctive query optimization method which includes the following steps: enabling an Hive to be combined with an HBase, achieving HBase table conjunctive querying through an HQL language provided by the Hive, then conducting optimization by setting parameters having influences on a bottom layer MapReduce task, and improving the conjunctive query performance. Compared with the prior art, the HBase table conjunctive query optimization method has the advantages that unnecessary programming trouble is reduced, parallel processing can be carried out on conjunctive query tasks, the query efficiency is improved, the practicability is high, and popularization is easy to achieve.
