A Head-to-Head Comparison: Hadoop vs. Spark

Open-Source

Apache Hadoop is an open-source Java-based software platform commonly used by many businesses to process and store enormous amounts of data. Elsewhere, the importance of Hadoop in the market assists organizations in making better decisions by analyzing numerous different data sources and variables. It gives companies an entire perspective of their business.

One of the significant advantages of Spark is the distributed design which can speed the processing process for large data sets. It’s a distributed computing engine that doesn’t have a single-machine design, but it does have the capability to operate in memory. Although it is speedy, Spark is not well designed for online or atomic transactions. Spark is ideal for batch jobs as well as data mining. Additionally, Spark is open-source, meaning it is entirely free to use in non-commercial ways.

Data Integration

In Apache Hadoop Ecosystem, Data Integration is a collection of procedures utilized to combine and retrieve information into useful and valuable data from different sources. Traditional data integration methods mainly were based on the ETL (extract transform, load, and) process that allows you to insulate and cleanse data and then load it into a warehouse.

Apache Spark is an open-source distributed processing system used for large-scale data processing. It can be used to decrease the time and cost to complete the ETL process. Spark uses an in-memory cache and optimized query execution to run quick queries against data of any size. Finally, we can conclude that Spark can be described as a general and fast engine designed for massive-scale data processing.

Fault Tolerance

Hadoop is exceptionally fault-tolerant because it was designed to replicate data over several nodes. Each file is broken down into blocks and repeated several times across different machines. If one machine fails, the file will be rebuilt from blocks on other devices.

Primarily RDD operations achieve Spark’s fault tolerance. Initially, data-at-rest is saved in HDFS that is fault-tolerant due to the architecture of Hadoop. When an RDD is constructed, it is a lineage that retains the way the dataset was created, and, since it’s indestructible, it can recreate it from scratch should the need arise. Data from Spark partitions is also constructed across nodes based on the DAG. It is replicated between executors and, in general, can be corrupted if the node or the communication between drivers and executors fails.

Speed

Spark software framework runs up to 100 times faster in memory and ten times more efficient in the disk. It’s also been utilized to sort through 100TB of data three times faster than Hadoop MapReduce, which is just one-tenth of all the computers. Spark is mainly discovered to be more efficient on machine learning applications, including Naive Bayes and K-means.

Ease of Use

Spark provides more than 80 high-level operations that make it simple to create parallel applications. Additionally, you can access it interactively using your Scala, Python, R, and SQL shells.

In Hadoop MapReduce, one must write lengthy codes compared to Spark to create parallel applications. Spark’s potential is available through an array of rich APIs specifically designed to allow quick and easy interaction with large amounts of data. These APIs are well documented and organized to make it easy for researchers and developers of applications to apply Spark in action swiftly.

Memory Consumption

There are many ways to optimize memory consumption within Hadoop and Spark. The first step in optimizing memory consumption is determining how much space is needed to store the data. You can accomplish this with an RDD by creating it, caching it, and checking the storage tab on the SparkUI. You can also check the logs of SparkContext and then use the Spark SizeEstimator to calculate how big the RDD is.

The memory usage of Spark has two main applications: processing and caching data from users. Therefore, it has to allocate memory for the two distinct kinds of data. One of the primary reasons for the increased memory usage of Spark is the sheer number of tasks it can perform. The internal memory management model lets it process any data in any cluster. As a default feature, Spark is optimized for massive amounts of data; however, you can modify Spark to process smaller amounts of data faster. The significant distinction in Spark and Hadoop in memory usage is that required by each. Both have efficient memory allocation and storage capacity; however, Spark is superior for older or low-resource clusters.

Latency

In the case of HDFS, as the request starts at the name node and then at the data nodes, there’s some delay in receiving the first bit of data. This results in a highly high latency rate when accessing data via HDFS.

Apache Spark 2.3 adds Continuous Processing into Structured Streaming, which will give you low-latency response times of about 1ms rather than the 100ms you’ll receive using micro-batching. Many Spark programs, e.g., machine learning and stream processing, need a low-latency operation. Spark applications use the BSP computation model and inform the scheduler at every task’s conclusion.
