Mapreduce Interview Questions

MapReduce is a processing methodology and a programming structure for distributed computing on java and the MapReduce algorithm comprises two important tasks, namely Map and Reduce. The map function takes a collection of data and converts it into another set of data, where specific elements are broken down into tuples (key/value pairs) and then; reduce task, which takes the product from a map as an input and connects those data tuples into a smaller set of tuples. As the flow of the name MapReduce indicates, the reduce task is always executed after the map job.

Hive Interview Questions

Apache Hive is an information repository software built above Apache Hadoop for implementing data query and analysis and provides SQL like interface to retrieve data saved in databases and file systems that combine with Hadoop. Moreover, conventional SQL queries must be executed in the MapReduce Java API to perform SQL applications and queries over distributed data. It gives the necessary SQL abstraction to unite SQL like queries into the underlying Java without the requirement to implement queries in the low-level Java API.

Sqoop Interview Questions

Sqoop is a command-line interface tool for conveying data between Hadoop and relational databases and bolsters loads of a single table as well as preserved jobs that can be operated multiple times to import updates made to a database since the latest import. Moreover, imports can also be employed to populate tables in Hive or HBase and exports can be practiced to set data from Hadoop into a relational database. Sqoop got the name from SQL-to-Hadoop and became a top-level Apache project in 2012.

Data Warehousing Interview Questions

Data warehousing is the process of constructing and managing a data warehouse and is constructed by integrating data from heterogeneous sources that encourage analytical reporting, structured or ad hoc queries, and decision making.

It also involves data cleaning, data integration, and data consolidations and there are decision support technologies that employ the data available in a data warehouse and these technologies help administrators to utilize the warehouse effectively and can gather data, analyze, and make conclusions based on the data in the warehouse. The information gathered in a warehouse can be utilized in any of the domains among; tuning production strategies, customer analysis, and operations analysis.

QlikView Interview Questions

QlikView is a leading business discovery platform and is unique in several ways as compared to the traditional BI platforms and as a data analysis tool, it manages the relationship between the data and the relationship can be seen visually and also shows the data that are unrelated. It renders both direct and indirect explorations by using specific searches in the list boxes.

QlikView's core and patented technology has the feature of in-memory data processing, which gives a superfast result to the users and accounts aggregations on the fly and summarizes data to 10% of the original size and also, neither clients nor developers of QlikView applications control the relationship between data and is handled automatically.

HBase Interview Questions

HBase is an open-source distributed database designed in Java succeeding Google's Bigtable and is a part of the Apache Software Foundation's Apache Hadoop project and runs on above HDFS (Hadoop Distributed File System), rendering Bigtable-like capabilities for Hadoop. Hbase produces a fault-tolerant way of stocking large volumes of sparse data (small amounts of information caught within a large collection of empty, like attaining the 50 largest items among 2 million records). Moreover, HBase features compression and Bloom filters on a per-column basis as described in the original Bigtable paper.

Hadoop Interview Questions

The Apache Hadoop develops open software for distributed computing and the Hadoop software library is a framework that grants for the distributed processing of bulk data sets across clusters of computers using simple programming styles. Moreover, it is devised to scale up from individual servers to thousands of machines, each offering limited computation and storage, rather than rely on hardware to fulfill high-availability, the library is designed to identify and handle failures at the application layer, so giving a highly-available service on top of a cluster of computers, each of which may be likely to failures.
