HCIA-Big Data study guide
HCIA-Big Data · Work through your exam, one topic at a time.
HCIA-Big Data is the Associate-level credential in Huawei's Career Certification portfolio, which Huawei describes as offering three levels: Huawei Certified ICT Associate (HCIA), Huawei Certified ICT Professional (HCIP), and Huawei Certified ICT Expert (HCIE). The associate tier is the entry point, aimed at students, career changers, and engineers who need a working vocabulary of the big data stack before specialising. Candidates typically cover the big data landscape and ecosystem, Hadoop and MapReduce fundamentals, Hive and data warehousing basics, HBase and NoSQL concepts, and FusionInsight platform operations. Expect scenario-based multiple-choice items rather than hands-on lab work at this level. The HCIA-Big Data study guide has 5 sections and about 1,443 words.
01Big Data Overview and the Ecosystem
This domain tests whether you can map a data problem onto the right components and explain the 4V/5V model, batch versus stream processing, and the collection–storage–compute–analysis–management layers of a Hadoop-centered stack. Expect terminology and architecture-matching questions rather than deep tuning.
274 words, about 1 min02Hadoop and MapReduce Fundamentals
This domain tests HDFS architecture, YARN resource management, and the MapReduce execution pipeline. You should know which daemon does what, how blocks and splits differ, and where shuffle, sort, combiner, and partitioner sit.
292 words, about 1 min03Hive and Data Warehousing Basics
This domain tests Hive's warehouse model, metastore, table types, partitioning and bucketing, file formats, and basic dimensional modeling. Expect questions on where data physically lives and what a DDL statement actually deletes.
313 words, about 2 min04HBase and NoSQL Basics
This domain tests the HBase data model, architecture, read/write path, and row-key design, plus the NoSQL family classifications. You must be able to choose HBase for random access rather than analytical scans.
278 words, about 1 min05FusionInsight and Big Data Operations
This domain tests day-to-day operation of a FusionInsight HD cluster through FusionInsight Manager: services, roles and instances, alarms, health checks, tenants, capacity, backup, and upgrades. Questions usually describe a symptom and ask for the correct operational response.
