![]() It resides on top of Hadoop to summarize Big Data, and makes querying and analyzing easy. Hive is a data warehouse infrastructure tool to process structured data in Hadoop. The Hive Query Language (HiveQL or HQL) for MapReduce to process structured data using Hive.The scripting approach for MapReduce to process structured and semi structured data using Pig.The traditional approach using Java MapReduce program for structured, semi-structured, and unstructured data.Note: There are various ways to execute MapReduce operations: Hive: It is a platform used to develop SQL type scripts to do MapReduce operations. ![]() Pig: It is a procedural language platform used to develop a script for MapReduce operations. Sqoop: It is used to import and export data to and from between HDFS and RDBMS. The Hadoop ecosystem contains different sub-projects (tools) such as Sqoop, Pig, and Hive that are used to help Hadoop modules. It provides a fault-tolerant file system to run on commodity hardware. HDFS:Hadoop Distributed File System is a part of Hadoop framework, used to store and process the datasets. MapReduce: It is a parallel programming model for processing large amounts of structured, semi-structured, and unstructured data on large clusters of commodity hardware. It contains two modules, one is MapReduce and another is Hadoop Distributed File System (HDFS). Hadoop is an open-source framework to store and process Big Data in a distributed environment. Therefore, the Apache Software Foundation introduced a framework called Hadoop to solve Big Data management and processing challenges. Using traditional data management systems, it is difficult to process Big Data. The term ‘Big Data’ is used for collections of large datasets that include huge volume, high velocity, and a variety of data that is increasing day by day. \rz replace text with given brush/register drag and draw with current brush (register) replace with a \, move up and left, and insert a \ replace with a /, move up and right, and insert a / replace with a /, move down and left, and insert a / replace with a \, move down and right, and insert a \ move down, inserting lines/space as needed move up, inserting lines/space as needed move right, inserting lines/space as needed ![]() move and draw down, inserting lines/space as needed move and draw up, inserting lines/space as needed move and draw right, inserting lines/space as needed DrawIt's number pad maps will expand the file as necessary to accomodate the drawing, automatically. When DrawIt is terminated it restores the user's maps and options. The components of DrawIt will then be placed where they belong, based on your Vim's runtimepath.ĭrawIt records many user options that affect DrawIt and all maps that starting DrawIt creates. After decompressing the file, edit it with Vim, and then source it (:so %). Using the shift-arrow keys, DrawIt will move the cursor, expanding lines and inserting spaces as needed, without changing underlying text.ĭrawIt is now in the vimball format, which is understood by the new Vim 7.0 release. DrC has written an ellipse-drawing Bresenham-style procedure: again, use the visual block selection to specify a box to contain the ellipse and \e to trigger the ellipse drawing.ĭrawIt incorporates an "erase" mode, toggled by the key, that will leave a trail of blanks behind and under the cursor as it is moved by the number pad. Use visual-block selection to specify starting and ending positions and a Bresenham line drawing algorithm will be used to connect the two. Viart's has been merged with the original DrawIt (vimscript#11) (by permission). DrawIt can also draw boxes and ellipses on a blank-filled area (DrawIt can produce these) which can be useful for drawing boxes around comments. The lines will be expanded as needed to accomodate your drawing. When DrawIt has been started you may use the number pad to leave a trail of dashes, vertical bars, etc. One may change the horizontal, vertical, slant, and crossing characters to whichever characters one wishes. Optionally one may "cap" the lines with arrowheads. DrawIt is a plugin which allows one to draw lines left, right, up, down, and along both slants.
