Apache beehive: In Hadoop, the only way to process data was with a MapReduce job. Likewise pig has its own language called pig Latin that turns yours too pig Latin script for a set of MapReduce jobs. Apache Sqoop: This is a tool used to import RDBMS data into Hadoop.
Likewise, you may be wondering why Pig is used in Hadoop?
pig is a high-level scripting language, ie Second hand with Apache Hadoop. pig enables data workers to write complex data transformations without knowledge of Java. pig simple SQL-like scripting language is called pig Latin and is aimed at developers who are already familiar with scripting languages and SQL.
What is hive in Hadoop?

What is the difference between Flume and Kafka?
Image from http://Kafka.apache.org. flume is a distributed, reliable and available system for efficiently collecting, aggregating and moving large amounts of data from many different sources into a central data storage such as HDFS or HBase. It is more tightly integrated with the Hadoop ecosystem.
What is Zookeeper in Cluster?
ZooKeeper is a centralized service for managing configuration information, naming, providing distributed synchronization, and providing group services. All of these types of services are used in some form of distributed applications.
What is Spark for in Hadoop?
spark runs on Hadoop, Apache Mesos, Kubernetes, standalone or in the cloud. It can access different data sources. you can run spark enabled using standalone cluster mode on EC2 Hadoop YARN, on Mesos or on Kubernetes.
What is Mapreduce for in Hadoop?
Hadoop MapReduce (Hadoop mapping/reduction) is a software framework for the distributed processing of large amounts of data on computing clusters using off-the-shelf hardware. It is a sub-project of Apache Hadoop Project. The framework takes care of scheduling tasks, monitors them and reruns any failed tasks.
What is yarn for in Hadoop?
YARN is a large-scale, distributed operating system for big data applications. The technology is designed for cluster management and is one of the key features in the second generation of Hadoop, the Apache Software Foundation’s open-source framework for distributed processing.
How many instances of Job Tracker can run on a Hadoop cluster?
JobTracker is the daemon service for sending and tracking MapReduce jobs in Hadoop. There is only one job tracker process run on every Hadoop cluster. Job tracker is running on its own JVM process. In a typical production clusters it is run on a separate machine.
What is Flume for in Hadoop?
A streaming service is registering Hadoop. Apache flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of streaming data into the Hadoop Distributed File System (HDFS).
What is Oozie for in Hadoop?
oozie is a workflow scheduler system for managing Apache Hadoop jobs. oozie Workflow jobs are directed acyclic graphs (DAGs) of actions. oozie Coordinator jobs are recurring oozie Workflow jobs triggered by time (frequency) and data availability. oozie is a scalable, reliable and expandable system.
What is the Impala in Hadoop?
impala is an open-source, massively parallel query engine based on clustered systems like Apache Hadoop. It was created based on Google’s Dremel paper. It’s an interactive SQL-like query engine that runs on it Hadoop Distributed File System (HDFS). impala uses HDFS as underlying storage.
What is Spark used for in Big Data?
Apache spark is an open source big data Processing framework built on speed, ease of use and sophisticated analytics. It was originally developed at UC Berkeley’s AMPLab in 2009 and released as open source as the Apache project in 2010.
What is Hbase and Hadoop?
HBase is her name Hadoop Database since it is a NoSQL database running on it Hadoop. It combines the scalability of Hadoop by running on the Hadoop Distributed file system (HDFS) with real-time data access as a key/value store and deep analytics capabilities from Map Reduce.
What is Hive QL?
the Hive query Language (HiveQL) is the primary data processing method for treasure data. HiveQL is powered by Apache beehive. Treasure Data is a cloud data platform that allows users to collect, store and analyze their data in the cloud.
What is HDFS for in Hadoop?
the Hadoop Distributed File System (HDFS) is the primary data storage system used by Hadoop applications. It uses a NameNode and DataNode architecture to implement a distributed file system that provides high-performance access to data over highly scalable systems Hadoop clusters.
What is hue used for in Hadoop?
hue is a web interface for analyzing data with Apache Hadoop. You can install it on any PC with anyone Hadoop Execution. hue is a suite of applications that provide web-based access to CDH components and a platform for building custom applications.
What is Apache Kafka for?
Apache™ Kafka is a fast, scalable, long-lived, and fault-tolerant publish-subscribe messaging system. Regardless of the industry or use case, Kafka mediates massive message streams for low-latency analytics in Enterprise Apache Hadoop.
What is Big Data Sqoop?
Sqoop (SQL-to-Hadoop) is a big data Tool that offers the possibility to extract Data from non-Hadoop Data saves, transform the Data into a Hadoop-usable form, and then load the Data in HDFS. This process is called ETL, for Extract, Transform, and Load.
What is the use of sqoop?
Sqoop is a tool for transferring data between Hadoop and relational database servers. it is used to Import data from relational databases such as MySQL, Oracle into Hadoop HDFS and export data from Hadoop file system to relational databases.
What does Apache mahout do?
Apache Mahout is an Apache Software Foundation project to create free implementations of distributed or otherwise scalable machine learning algorithms, primarily focused on the areas of collaborative filtering, clustering, and classification. Many of the implementations use Apache Hadoop Platform.
What is replication factor?
Hadoop Distributed File System (HDFS) stores files as blocks of data and distributes those blocks across the cluster. If for example the replication factor was set to 3 (default in HDFS), there would be one original block and two replicas.
What is Hcatalog for?
hcatalogue is a table storage management tool for Hadoop that makes the Hive metastore’s tabular data available to other Hadoop applications. It allows users with various data processing tools (Pig, MapReduce) to easily write data to a raster.
