Insert Text data into HDFS file structure

In this post I am going to insert below text file data into HDFS folder.File name is Sample.txt

id,Name,City,email
1,Pubudu,Colombo,pubududewagam@gamil.com
2,Suranga,Colombo,pubududewagam@gamil.com
3,Dewagama,Colombo,pubududewagam@gamil.com

Then create a folder in the HDFS file structure.
Coomand:-

hdfs dfs –mkdir /mydatafolder

To verified the file creation we can use below command.

hdfs dfs –ls /

To copy the text data you can use copyFromLocal command as below.

hdfs dfs -copyFromLocal C:\Users\pubudu\Desktop\test.txt /mydatafolder

To verify the uploaded file, you can use below command.

hdfs dfs –ls /mydatafolder

To view the content of the file we can use below command.

hdfs dfs –cat /mydatafolder/test.txt

Thank you !!!
