Digitized with Aadhar card. The details of driving license

Digitized India is used to connect rural
areas with high speed Internet. As a result, it is used to reduce crime, manual
power, documentation and also increases the job opportunities.  Nowadays people are facing many problems when
they forget to carry the driving license and also to reduce the corruption, the
proposed system combines the driving license with Aadhar card. The details of
driving license and Aadhar card data can be combined using the MapReduce
Counters. It automatically aggregated over Map and Reduce phases. It is used to
create a tool that manages the handling of license using unique identification
associated with each individual. It helps the user to travel various places
without having the license. So the proposed system will make the digitization
of data on a large scale for easy and quick access throughout the India. Sqoop
is a tool intended to exchange information amongst Hadoop and social databases.
Sqoop utilizes MapReduce to import and export the information, which gives
parallel operation and in addition adaptation to non-critical failure. As the
result of parallel operations time utilization for transferring the data get
decreased radically.

Internet organizations routinely create many tera-bytes of logs and operation
records. MapReduce is a programming model for processing large data set in
distributed and parallel processes stored inside the Hadoop distributed file
system 13. Map Reduce has ended up being a powerful device to process such
expansive informational indexes. Map Reduce has been widely used in various
applications, including web indexing, log analysis, data mining, scientific
simulations, machine translation, etc 7. There are several parallel computing
frameworks that support Map Reduce, such as Apache Hadoop, Google Map Reduce,
and Microsoft Dryad, of which Hadoop is open-source and widely used 7.Hadoop is an open
source framework for processing and analysing of big data with the help of HDFS
and MapReduce. The traditional database is stored in an RDBMS like Oracle, MS
SQL Server or DB2 and a enhanced and sophisticated software will be written to
interact with the database, process the desired data and present it to the
users for the purpose of analysis8. Apache Hadoop is
developed for not only structured datasets but it can also process unstructured
datasets. NoSQL database has turned into a popular distributed database
framework that pulled in numerous considerations among endeavours and
scientists. Database engineers in many organizations consider about the movement
of relational databases to NoSQL databases for the effectiveness of taking care
of enormous information.                 NoSQL databases have emerged as a
solution to the aforementioned drawbacks and have become the preferred storage
option for big data applications. Currently, there are more than 225 recognized
NoSQL databases 18. The basic operations in a database can be formulated from
one or more of the following: Create, Read, Update and Delete (commonly
referred as CRUD). Data stores can be tailored to handle varied workloads of
CRUD operations to satisfy the requirements of specific applications.
Therefore, it is necessary to identify, among the available databases, the
optimal NoSQL database for a given application workload. Apart from the
Hadoop services, the Hadoop Ecosystem also includes various other tools as per
the particular requirements. The other tools which are part of the ecosystem
are namely Hive, Pig, Flume, Zookeeper, HBase etc 17. Hive is an information
distribution centre programming venture based over Apache Hadoop for giving
information summary, inquiry, and analysis. Hive gives a SQL-like interface to
question information put away in different databases and record frameworks that
incorporate with Hadoop. Traditional SQL inquiries must be actualized in the
MapReduce Java API to execute SQL applications and questions over dispersed
information. Hive gives the important SQL reflection to coordinate SQL-like inquiries
(HiveQL) into the basic Java without the need to implement queries in the
low-level Java API. Here, Sqoop
underpins incremental heaps of a table or SQL queries and additionally spared
occupations which can be run various circumstances to import refreshes made to
a database since the last import. Imports can likewise be utilized to populate
tables in Hive or HBase. Sqoop got the name from sql+hadoop. Sqoop import and
export tools are used to import and export the data. 

In this paper we
address the issue of effectively handling MapReduce occupations with complex
reducer undertakings over skewed information. The information skew issue in MapReduce
has been contemplated. When MapReduce keeps running in a virtualized cloud
registering environment, for example, Amazon EC2, the registering and capacity
assets of the hidden virtual machines (VMs) can be differing for an assortment
of reasons.
