Excellent video! These low-level explanations are greatly appreciated.
Thank You for the detailed explanation.
Are we still using RDD when we have DF or DS ?
Good explained but how can we decided how many mapper should be used?
great info! well explained
If we arre using hive for data cleansing and data preparation part and spark for data analysis part then how we can schedule our hive and spark jobs in way that data first automatically get prepared by hive and then spark jobs for data analysis if we are receiving data on daily basis.
