Hi,
You can create one directory in HDFS using the command “hdfs dfs -mkdir <path>” and, then use the given below command to copy data from the local file to HDFS:
$ hdfs dfs -put /root/Hadoop/sample.txt /"your_hdfs_dir_path"
Alternatively, you can also use the below command.
$ hdfs dfs -copyFromLocal /root/Hadoop/sample.txt /"your_hdfs_dir_path
For details, You can even check out Hadoop Ecosystem tools with the Online big data courses.
