First of all i would like to thank Durga sir @itversity whose tutorials and support made it possible.
i would also like to thank each and every one whom i have interacted with for clearing my doubts.
Exam take away:
1)no matter how much confident you are in any module , please practice with each and every scenario.
dont assume if you can successfully query your code with a particular scenario you can also perform the rest without practicing . even if it is a simple sqoop-import/export try your hands on all the different , datafile type, delimiter type . etc . it took me some time to figure out a simple sqoop import delimiter , though the night before iwas fully confident that i know all the datatypes and delimiters . while typing it in the exam you might find it difficult if you have not practiced with.
2)you might be reading this everywhere that time management is the key , yes it is . so plan accordingly your strategy .
3)the text in the question would be really small and the table/database names would be hardly visible .
- ONE TIP: open all the 10 questions in 10 different tabs , and when you have launched one code (it will take some time to execute) by that time go to the next tab read the question and decide if you can answer it or not and by the time ur first code executes fully you should be ready with the next question to answer.
5)check all the output and file format at that very time , donot keep it till the end. you wont get enough time to comeback and check your answers , because for that you have to read the question again as the location and variables are different for every question.
6)i was able to attempt 9 questions completely and when i was on the 10th one and was just about to execute it my time was up. so i attempted 9 questions and i was very confident on that.
result came after like 1 hour and to my dismay out of the 9 attempted 2 questions were wrong( i dont know how but the score sheet showed as incorrect ) one was wrong data for sqoop import , though i had validated the count and some sample records and the other was incorrect schema in hive which too i had verified the data . so i was just lucky to be stuck at 7 correct questions .
last but one important thing. keep calm no matter what and aim to attempt questions correctly and validate the output path and sample data that very moment .
thank you once again to every one and this wonderful community .
