Overview of Hadoop Hive Training:

Why Hive?

The problem was for processing and analyzing data, users found it difficult to code is not all of them were versed with the coding languages, if processing and analyzing and the solution was required a language similar to SQL which was well known to all the users and thus the Hive or HQL language evolved.

 
What is Hive?

Hive is data warehouse system which is used for querying analyzing large data set stored in the HDFS or the Hadoop file system. Hive uses a query language that we call hive QL or HQL that is similar to SQL. The user sends Hive queries and that is converted into a MapReduce tasks and then accesses the Hadoop Mapreduce system.

Learn Architecture of Hadoop Hive Training:

Hive Clients supports different types of clients applications in different languages prefer for performing queries. Thrift is a software framework, hive server is based on thrift, that’s why it can serve the request from all programming language that support thrift and then also have JDBC application and the Hive JDBC driver. Java Data Base Connectivity application connects through the JDBC Driver. The Hive ODBC driver or open database connectivity application is connected through the ODBC driver. Hive supports various services they all connect into the Hive server and the Hive web interface is a GUI is provided to execute hive quires. The CLI is a direct terminal window and it will also show two different interface works. The Hive Driver is responsible for all the queries submitted.

 
Hive Driver is performs three steps internally
  • Compiler: hive driver passes query to compiler where it is checked and analyzed
  • Optimizer: The optimized logical plan in the form of a graph of MapReduce and HDFS tasks is obtained.
  • Executor: Executer in the final step, the tests are executed

Processing and resource management there are all handled by the MapReduce V1 and MapReduce V2 the Yarn and tests. These are all different ways of managing these resources depending on what version of Hadoop. Hive uses MapReduces framework to process queries and distributed storage which is the HDFS.

 

Data Flow in Hive Training:

Hive in the Hadoop system and underneath the user interface or UI, we have in that driver or compiler or execution engine and Metastore. They are all goes into the MapReduce and the Hadoop system. The execution a query goes into the Driver and plan what are going to do refer to the query execution.  Metadata is looking at where the data located is and what is the schema. The metadata into the compiler then compiler takes all that information and SendPlan returns it to the driver. The Driver sends the execute plan to the execution engine. Once it’s in the execution engine, the execution in it acts as a bridge between Hive and Hadoop to process the query and that going into your MapReduce in your Hadoop file system or HDFS. The execution engine communications is bi-directionally with the Meta stored perform operations like create, drop, tables, metastore or stores information’s about tables and columns. 

 

Hive Data Modeling in Hadoop in Hive Training:

Hive Data Modeling have Tables, Partitions, and buckets, the tables in hive are created the same way to done in RDMS. The traditional server, MYSQL server and enterprise equipment and lot of people pulling and removing service of there. The tables are going to look very similar and this makes it very easy to take that information and need to keep current information .
