The hadoop fs -df -h command in HDFS (Hadoop Distributed File System) is used to display the disk space used and disk space available in a human-readable format. The -df option is used to show disk usage statistics and the -h option is used to display the output in a human-readable format (i.e., using units such as MB, GB, TB, etc.).
Here’s an example of the output of the hadoop fs -df -h command:
In this example, the HDFS file system has a total size of 16.5 TB, with 6.9 TB used and 8.7 TB available. The usage percentage is calculated as Used / (Used + Available) * 100, which is 42% in this case.
The hadoop fs -du -h command in HDFS (Hadoop Distributed File System) is used to display the disk space used by a particular directory or file in a human-readable format. The -du option stands for “disk usage” and is used to show the space used by a directory or file, and the -h option is used to display the output in a human-readable format (i.e., using units such as MB, GB, TB, etc.).
Here’s an example of the output of the hadoop fs -du -h command:
The hadoop fs -du -s -h command in HDFS (Hadoop Distributed File System) is used to display the disk space used by a particular directory in a summarized, human-readable format. The -du option stands for “disk usage” and is used to show the space used by a directory, the -s option is used to summarize disk usage by summing up the size of all files in the directory, and the -h option is used to display the output in a human-readable format (i.e., using units such as MB, GB, TB, etc.).
