Hadoop 2x vs 3x top differences

-
In many interviews, the first question for Hadoop developers is what are the differences between Hadoop 2 and 3. You already know that Hadoop upgraded from version 1.

Hadoop features


The below list is useful to know the differences. I have given Hadoop details in the form of questions and answers so that beginners can understand.

Hadoop 2.x Vs 3.x


hadoop v2 vs 3
The major change in hadoop 3 is no storage overhead. So, you may be curious about how Hadoop 3 is managing storage.

My plan is for you is first to go through the list of differences and check the references section, to learn more about Hadoop storage management.

I have shared 7 amazing AWS interview questions for your quick reference. 1). What is AWS? Amazon Web Services (AWS) provides on-demand computing resources and services in the cloud, with pay-as-you-go pricing. For example, you can run a server on AWS that you can log on to, configure, secure, and run just as you would a server that's sitting in front of you 2). What you can do with AWS? Store public or private data. Host a static website. These websites use client-side technologies (such as HTML, CSS, and JavaScript) to display content that doesn't change frequently. A static website doesn't require server-side technologies (such as PHP and ASP.NET). Host a dynamic website or web app. These websites include classic three-tier applications, with web, application, and database tiers. Support students or online training programs. Process business and scientific data. Handle peak loads. AWS Questions 3). What is the Security group? A security group acts as a virtual fi

How to Fix Python Syntax Errors Quickly

In Python, you can call parsing errors Syntax errors. How to fix the syntax errors quickly, I can show in this post. Also, check Python Syntax Errors Cheat Sheet. Python Syntax Error. If you run the Python code, the interpreter first parses the logic. If any errors found, it is the developer's responsibility to fix them. Courtesy: Python documentation. >>> while True print('Hello world')   File "<stdin>", line 1     while True print('Hello world')                    ^ SyntaxError: invalid syntax How to Fix the Syntax Error First, check for the line number. In the above case, it is '1'. Then look for the symbol '^'. The issue is at the PRINT function. The reason is before the PRINT function you need a colon ':'. That is the reason, you are getting error. This is a syntax error. Find below the corrected logic: >>> while True : print('Hello world')   File "<stdin>", line 1     while Tr

Python 'getsizeof' Command the Real Purpose

In Python, there are many objects. Out of those List (arrays) is one type.  To get the number of elements present in a List is not easy. So how to get this? To do you need the 'getsizeof' command. Import 'sys' Library. You need to import the 'sys' library to use the SIZE commands.  >>> import sys Congrats to you since you have now imported the SYS library. The command name is " getsizeof" . Check the below example. print("An Integer:") i = int(100) print(sys.getsizeof(i)) The result will be: 100 What is the size command?  - is to get the size of elements. It gives the result based on the object you are being used. Suppose, if you use Strings, you will get String length. How to use the  'getsizeof' command? Example:1 print("Empty string:") empty_string = "" print(sys.getsizeof(empty_string)) Example:2 print("A normal string") s = "Hello world" print(sys.getsizeof(s)) Example:3 print(&quo

How to Check Log File in Kafka

In Kafka, the log file's function is to store entries. Here, you can find entries for the producer's incoming messages. These log files you can call as topics. Again topics are divided into partitions. IN THIS PAGE Kafka Logs How Producer Messages Store Benefits of Kafka Logs How to check Logs in Kafka 1. Kafka Logs The mechanism underlying Kafka is the log. Most software engineers are familiar with this. It tracks what an application is doing.  If you have performance issues or errors in your application, the first place to check is the application logs. But it is a different sort of log.  In the context of Kafka (or any other distributed system), a log is "an append-only, totally ordered sequence of records - ordered by time. 2. How Producer Messages Store The producer writes the messages to Kafka, the records store in a log file. The records sored as 0,1,2,3 and so on. 4. Benefits of Kafka Logs Logs are a simple data abstraction with powerful implications. If you have r

5 HBase Vs. RDBMS Top Functional Differences

HBASE in the Big data context has a lot of benefits over RDBMS. Clear difference makes you feel great why you need HBASE in Hadoop or Bigdata platform. Let us check one by one quickly. HBASE Vs. RDBMS HBase handles a large amount of data that is store in a distributed manner in the column-oriented format while RDBMS is systematic storage of a database that cannot support a random manner for accessing the database. RDBMS strictly follow Codd's 12 rules with fixed schemas and row-oriented manner of database and also follow ACID properties, while HBase follows BASE properties and implement complex queries. Secondary indexes, complex inner and outer joins, count, sum, sort, group, and data of page and table can easily be accessible by RDBMS. From small to medium storage application there is the use of RDBMS that provide the solution with MySQL and PostgreSQL whose size increase with concurrency and performance. Codd's rules always need to keep in mind while extending the size of th

Python Dictionary Vs List With Examples

-

Dictionary and List we use interchangeably in Python to store values. For beginners, both look the same. In reality, they both differ. I want to share some key differences between Python Dictionary and List . Python Dictionary Vs List Top Differences. Values in lists are accessed by means of integers called indices, which indicate where in the list a given value is found. Dictionaries access values by means of integers, strings, or other Python objects called keys , which indicate where in the dictionary a given value is found.  In other words, both lists and dictionaries provide indexed access to arbitrary values, but the set of items that can be used as dictionary indices is much larger than, and contains, the set of items that can be used as list indices.  Also, the mechanism that dictionaries use to provide indexed access is quite different from that used by lists. Both lists and dictionaries can store objects of any type. Values stored in a list are implicitly ordered by their p

Linux Relative Vs. Absolute Path Top Differences

Linux directories are helpful to store files. Many a time, the programmer would trade in directory paths. The paths are two types - absolute and relative. I have shared simple ideas to remember the differences between these two. Linux Absolute Vs. Relative Path in Linux Below are the differences between these two. 1. Absolute pathname An example is /usr/lib, which is an exact directory in the directory tree.  Think of the absolute pathname as being the complete mailing address for a package that the postal service will deliver to your next-door neighbor. 2. Relative pathname An example is cups, which represents the cups subdirectory of the current directory, whatever that may be.  Think of the relative directory name as giving the postal carrier directions from your house to the one next door so that the carrier can deliver the package. Useful differences, how to differentiate the differences between absolute and real paths. How to go back to the home directory If I type  cd cups  in

TTY(Terminal name) - associated with this process TIME(Time) - the format is hh: mm: ss (Hours, Minutes, and Seconds). Cumulated time of that particular process.
