Best Spark Coders, Specialists for Hire in Ukraine

It is a high-performance data processing engine that is stored in the Hadoop cluster. Compared to Hadoop’s MapReduce mechanism, Spark provides more performance when processing data in memory. The programme can be executed on the nodes of the Hadoop cluster using Hadoop YARN and in a separate mode. Supports processing of data in HDFS, HBase, Cassandra, Hive repositories in any Hadoop input format (InputFormat). Spark can be used both in typical data-processing scenarios similar to MapReduce and for implementation of specific methods such as streaming, SQL, interactive and analytic queries, machine learning tasks and graph work. The Spark application consists of a driver process (process driver) and many processors. Spark can work in local mode, in which they all run on one computer with one executor on each processor core, and the cluster’s work is only emulated. Typically, this mode is used for development or testing, when distributed storage is not needed and instead the local file system is used. For distributed storage, Spark can connect to a variety of systems, including Hadoop Distributed File System, MapR File System, Cassandra, OpenStack Swift, Amazon S3, Kudu, or implementation of the original solution.

Questions and Answers related to Spark Development

How reliable is Spark?

“If you mean reliable in the sense of fault-tolerance, Spark is designed to support the loss of any set of worker nodes. It will rerun any tasks those nodes were executing, and recompute any data it had cached on them. Spark is also designed to work if the data does not fit in memory, in which case it can spill it to disk. If you mean reliable as in “will it crash on me”, any software has bugs…”

Is Spark a good solution to replace Informatica ETL in EDW?

“Yes, Spark is a good solution. But Spark alone cannot replace Informatica, it needs the help of other Big Data Ecosystem tools such as Apache Sqoop, HDFS, Apache Kafka etc. One of the backdraws of Hadoop Eco system is that offers bad performance for interactive querying. So a database such as Cassandra has to be maintained with data needed for reports.”

Will Spark overtake Hadoop? Will Hadoop be replaced by Spark?

“Apache Spark is growing very quickly and replacing MapReduce. Apache Spark is much-advance cluster computing engine than MapReduce. Spark can handle any type of requirements such as batch, interactive, iterative, streaming, graph while MapReduce limits to Batch processing…”

What are the pros and cons of Apache Spark?

“Before we learn what are the disadvantages of Apache Spark, let us learn advantages of Apache Spark. In Spark Streaming, the arriving live stream of data is divided into batches of pre-defined interval, and each batch of data is treated like Spark Resilient Distributed Database (RDDs). Then these RDDs are processed using the operations like map, reduce, join etc. The result of these operations is returned in batches. Thus, it is not real time processing but Spark is near real time processing of live data…”
