[@TechnologicalGeeksHindi]

+Tech With Me Thank you bro , Actually Jo jar files hamne import karwai hai un jar files ke under mapreduce ke methods hai , aur is wale program me teen methods use ki hai map , reduce aur main method , aur Jo program ka flow hai wo main method me mention kiya gaya hai , Actually ye video mapreduce ke theory video pr based hai Jo Maine is video se pehle upload kiya hai , I'll suggest you to watch that video and java basics for hadoop once 😊 For any query you can contact me [e-mail]

[@dharmendranamdev4562]

as you said mapper takes input as (intwritable,text) format but you didn't specify such format in your text file.could you please make me understand

[@TechnologicalGeeksHindi]

We don't have to specify anything in text file , the mapreduce is designed in such a way that it will automatically read using the InputFormat class

[@jeskipurohit8555]

[@ankitamorey1838]

Sir I am going to join hadoop developer course, if I have interest in pig hive etc but not mapreduce that much, so when I get job I have to work on mapreduce also? Or only scripting languages like pig hive etc. Because in a video of edureka I saw that hive is used for structured data, pig for structured and semi structured data and mapreduce for all data types .pls answer asap

[@TechnologicalGeeksHindi]

+ankita morey hive is recommended for structured data and pig for structured and semi structured data , that's right , however we can use UDF for processing unstructured data in both pig and hive. Good knowledge of mr is always a plus point.

[@rahulshandilya880]

give me all input file format and out file format example video in detail
