Interviewer started to ask questions based on what i have kept in resume. His questions started from basic to advanced. What is bucketing and partitioning and use cases? Difference between group and co group in Pig ? Day to day activities in my job? Project flow ? Accumulators and broad cast variables in spark? How spark is fault tolerant? Distributed cache in hadoop? What types of fileformats used in hive? Default mappers in sqoop? How much of data you handle daily or monthly? Why hive and pig used? On Map reduce basic programming? like how you will write program just to test your knowledge on MapReduce. If you store file from HDFS to pig using PIGSTORAGE in grunt shell but if that file is not actually available in that HDFS path will it work?
