Find out the results, and discover which option might … So, it would be safe to say that Impala is not going to replace Spark soon or vice versa. Hive can now be accessed and processed using spark SQL jobs. Big data face-off: Spark vs. Impala vs. Hive vs. Presto. If you want to insert your data record by record, or want to do interactive queries in Impala then Kudu is likely the best choice. Now it boils down to whether you want to store the data in Hive or in Kudu, as Spark can work with both of these. AtScale recently performed benchmark tests on the Hadoop engines Spark, Impala, Hive, and Presto. The goals behind developing Hive and these tools were different. Spark uses RDD (Resilient Distributed Datasets) to keep data in memory, reducing I/O, and therefore providing faster analysis than traditional MapReduce jobs. Hive was never developed for real-time, in memory processing and is based on MapReduce. The Complete Buyer's Guide for a Semantic Layer. Impala is developed and shipped by Cloudera. It’s just that Spark SQL can be seen to be a developer-friendly Spark based API which is aimed to make the programming easier. Hive, Impala and Spark SQL all fit into the SQL-on-Hadoop category. Hive Vs Mapreduce - MapReduce programs are parallel in nature, thus are very useful for performing large-scale data analysis using multiple machines in the cluster. The findings prove a lot of what we already know: Impala is better for needles in moderate-size haystacks, even when there are a lot of users. It is an advanced analytics language that would allow you to leverage your familiarity with SQL (without writing … Spark, Hive, Impala and Presto are SQL based engines. Today AtScale released its Q4 benchmark results for the major big data SQL engines: Spark, Impala, Hive/Tez, and Presto.. So answer to your question is "NO" spark will not replace hive or impala. Apache Hive: It is a data warehouse software project built on top of Apache Hadoop for providing data query and analysis. Comparison between Hive and Impala or Spark or Drill sometimes sounds inappropriate to me. For this Drill is not supported, but Hive tables and Kudu are supported by Cloudera. Impala queries are not translated to MapReduce jobs, instead, they are executed natively. It was built for offline batch processing kinda stuff. The final comparison I wanted to evaluate was In-Database performance of using Hive (MapReduce & YARN), Impala (daemon processes), and Spark. As far as Impala is concerned, it is also a SQL query engine that is designed on top of Hadoop. Conclusion. Hive has its special ability of frequent switching between engines and so is an efficient tool for querying large data sets. Get a thorough walkthrough of the different approaches to selecting, buying, and implementing a semantic layer for your analytics stack, and a checklist you can refer to as you start your search. and Spark is mostly used in Analytics purpose where the developers are more inclined towards Statistics as they can also use R launguage with spark, for making their initial data frames. Apache Hive and Spark are both top level Apache projects. We cannot say that Apache Spark SQL is the replacement for Hive or vice-versa. Spark which has been proven much faster than map reduce eventually had to support hive.
