Big data face-off: Spark vs. Impala vs. Hive vs. Presto. Find out the results, and discover which option might … It is an advanced analytics language that would allow you to leverage your familiarity with SQL (without writing … AtScale recently performed benchmark tests on the Hadoop engines Spark, Impala, Hive, and Presto. 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. Spark which has been proven much faster than map reduce eventually had to support hive. 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. Spark, Hive, Impala and Presto are SQL based engines. The final comparison I wanted to evaluate was In-Database performance of using Hive (MapReduce & YARN), Impala (daemon processes), and Spark. 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. Today AtScale released its Q4 benchmark results for the major big data SQL engines: Spark, Impala, Hive/Tez, and Presto.. Hive, Impala and Spark SQL all fit into the SQL-on-Hadoop category. So, it would be safe to say that Impala is not going to replace Spark soon or vice versa. Conclusion. 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. It was built for offline batch processing kinda stuff. Hive was never developed for real-time, in memory processing and is based on MapReduce. So answer to your question is "NO" spark will not replace hive or impala. Hive has its special ability of frequent switching between engines and so is an efficient tool for querying large data sets. 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. Apache Hive and Spark are both top level Apache projects. 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. Comparison between Hive and Impala or Spark or Drill sometimes sounds inappropriate to me. Spark uses RDD (Resilient Distributed Datasets) to keep data in memory, reducing I/O, and therefore providing faster analysis than traditional MapReduce jobs. The goals behind developing Hive and these tools were different. Hive gives a SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop. As far as Impala is concerned, it is also a SQL query engine that is designed on top of Hadoop. 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. Hive can now be accessed and processed using spark SQL jobs. Apache Hive: It is a data warehouse software project built on top of Apache Hadoop for providing data query and analysis. 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. Impala is developed and shipped by Cloudera.
