Top Apache HIVE excellent built-in features for Big data
#Top Apache HIVE excellent built-in features for Big data:
Apache Hive aids examination of great datasets kept in Hadoop’s HDFS and harmonious file setups such like Amazon S3 filesystem.

It delivers an SQL-like lingo named when keeping complete aid aimed at map/reduce. To accelerate requests, it delivers guides, containing bitmap guides.

By preset, Hive stores metadata in an implanted Apache Derby database, and different client/server databases like MySQL may optionally be applied.

Currently, there are 4 file setups maintained in Hive, that are TEXTFILE, SEQUENCE FILE, ORC and RCFILE.

 Other attributes of Hive include:

  • Indexing to supply quickening, directory sort containing compacting and Bitmap directory as of 0.10, further directory kinds are designed.
  • Different depository kinds such like simple written material, RCFile, HBase, ORC, and other ones.
  • Metadata depository in an RDBMS, notably decreasing the time to accomplish verbal examines throughout request implementation.
  • Operating on compressed information kept in to Hadoop environment, set of rules containing gzip, bzip2, snappy, etcetera.
  • Built-in exploiter described purposes (UDFs) to manipulate dates, cords, and different data-mining implements. Hive aids expanding the UDF set to cover use-cases not maintained by integrated purposes.
  • SQL-like requests (Hive QL), that are completely changed in to map-reduce appointments.

Automation developer these are top Skills you need to learn

By
Robotic process automation is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tool. So, learn anyone tool to start your career in automation.
To get a job in this line, I found in my research that some programming skills and Hand-on training on any one of the tools is required. Also, try to know the differences between popular RPA tools.
Skills Companies Looking in Automation Engineers All big companies looking for candidates having experience in Automation anywhere, Blue Prism and UIPath. It is not possible to learn all tools. Learn anyone tool and do practice well.

Ok.

You may ask a question about how to do it. Join in good training institute and learn one tool.  Take online classes to learn faster.

To learn Uipath try here. Also, you can enroll online course to learn UiPath.

Three popular RPA tools functional differences

By
Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.

BluePrism Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. The technology is scalable, secure, resilient, and flexible and is supported by a comprehensive methodology, operational framework and provided as packaged software.The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ens…

SQL queries how to use built-in functions correctly

By
In this post I am giving top examples on SQL functions. About built-in functions, I have covered in my previous post.
List of examples:DATE-TIME functionsNumeric functionsChar functionsNull-related functions1. DATE/TIME functions SELECT p_code, launch_dt, CURRENT_DATE FROM product; CURRENT_DATE returns current date.
SELECT p_code, TO_CHAR(launch_dt, 'DD MONTH YYYY') reformatted_dt FROM product; TO_CHAR function returns DATE in CHAR format.
2. Numeric functions SELECT p_code, price, (price - 20), ABS(price - 20.00) FROM product; ABS - function returns absolute value
SELECT p_code, price, ROUND (price, 1) FROM product;
ROUND function - Round to 1 digit.
SELECT p_code, price, SIGN(price - 15) FROM product;
SIGN function - It returns sign; either + or -
SELECT p_code, price, TRUNC(price, 1) FROM product;
TRUNC function - Truncates to a certain number of decimal places.
3. CHAR functions SELECT p_code, CONCAT(CONCAT(p_name, ' -- ') , price) FROM product; CONCAT function - co…

Python Improved Logic Easy Way to Calculate Factorial

By
I am practicing Python programming. This post is you can write logic to calculate factorial in function. This function you can call it a user-defined function. The function name is 'factorial.py'. In real-time, you can write a program in a file and run it in python console. The main task of a developer is to create functions for the reusable code. They call these functions whenever they need. Factorial calculation program for supplied input value. Factorial Logic in Python I have completed this logic in 3 steps. Write factorial.pyImportExecute it Write Factorial.py  Here you need to define a function. Use 2 for loops, and write your logic. This is done on LInux operating system. You can also try on Linux.
After, ESC command Use, :wq to come out of the module. Import Factorial.py Go to Python console, using 'python' command. Use import factorial.py command.


Execute Factorial.py  >>> factorial.fact(5) It will show the result of factorial. Bottom line  Factorial o…
