Add folders with files to Hadoop Cluster




I have large no of files. Data is NASDAQ Stock data from 1999 till date. I have data in folders. Ex: 1999 Folders will have months and month folder will have files.
So I will have 25 Years folders, and in each year folder I have 12 months folders and in each month I will have files.
How do I load these files into Hadoop in a single shot and also, is there a way to load all the files into one folder in Hadoop/Spark.



The files inside are in CSV Format


In ambari go to Files view.
under user
under radhakrishna (username)
You can add new folder and upload the files.

Refer below screenshot for better understanding.
