Speed. In Hadoop, all the data is stored in Hard disks of DataNodes. Apache hive uses a SQL like scripting language called HiveQL that can convert queries to MapReduce, Apache Tez and Spark jobs. While Pig is basically a dataflow language that allows us to process enormous amounts of data very easily and quickly. Comparing Hadoop vs. Hive is an open-source engine with a vast community: 1). The features highlighted above are now compared between Apache Spark and Hadoop. Hive uses MapReduce concept for query execution that makes it relatively slow as compared to Cloudera Impala, Spark or Presto Spark with cost in mind, we need to dig deeper than the price of the software. Spark vs Hadoop: Performance. ... A Blend of Apache Hive and Apache Spark. Whenever the data is required for processing, it is read from hard disk and saved into the hard disk. Spark is a fast and general processing engine compatible with Hadoop data. The capabilities of either tool were not fully transparent to both companies at the early stages of development which resulted in the overlap.

But Spark did not overcome hadoop totally but it has just taken over a part of hadoop which is map reduce processing. Although Pig (an add-on tool) makes it easier to program, it demands some time to learn the syntax. Pig and Hive were developed by Yahoo and Facebook respectively to solve the same problem (i.e. The choice for 'procedural dataflow language' vs 'declarative data flow language' is also a strong argument for the choice between pig and hive.
