HDFS find
In Hadoop Distributed File System (HDFS), there is no built-in command or tool specifically named “find” for searching files or directories as you might find in typical Unix-like file systems. However, you can achieve similar functionality using the hadoop fs
command and a combination of other commands or tools available in the Hadoop ecosystem.
One way to search for files or directories in HDFS is by using the hadoop fs -ls
command to list the contents of a directory and then filter the results based on your search criteria. Here’s an example of how you can do this:
hadoop fs -ls -R /path/to/start | grep "search_term"
-ls -R
is used to recursively list all files and directories under the specified starting directory (/path/to/start
).grep "search_term"
filters the list to include only entries that match the search term you specify.
For instance, if you want to find all files or directories with “example” in their name under the /user/hadoop
directory, you can use:
hadoop fs -ls -R /user/hadoop | grep "example"
This command will list all entries containing “example” in their name within the /user/hadoop
directory and its subdirectories.
Please replace /path/to/start
and "search_term"
with the appropriate path and search criteria for your specific use case.
