Is there a way to locate a specific file in hadoop?

I know, that I can use this: hadoop fs -find /some_directory

But, is there a command like this: hadoop locate some_file_name?

hadoop fs -ls defaults to /user/userName, so you can leave the path blank to view the contents of your home directory.

hadoop fs -ls

 

To find a file in the Hadoop Distributed file system:

hdfs dfs -ls -R / | grep [search_term]

In the above command,

-ls is for listing files

-R is for recursive(iterate through sub directories)

/ means from the root directory

| to pipe the output of first command to the second

grep command to extract matching strings

[search_term] file name to be searched for in the list of all files in the hadoop file system.

Alternatively the below command can also be used find and also apply some expressions:

hadoop fs -find / -name test -print

Finds all files that match the specified expression and applies selected actions to them. If no path is specified then defaults to the current working directory. If no expression is specified then defaults to -print.

The hadoop fs -ls command allows you to view the files and directories in your HDFS filesystem, much as the ls command works on Linux / OS X / *nix. A user's home directory in HDFS is located at /user/userName. For example, my home directory is /user/akbar.

If you are looking for equivalent of locate Linux command than such option does not exist in Hadoop. But if you are looking for the way of how to find specific file you can use name parameter of fs -findcommand for this:

hadoop fs -find /some_directory -name some_file_name

If you are looking for the actual location of hdfs file in your local file system you can use fsckcommand for this:

hdfs fsck /some_directory/some_file_name -files -blocks -locations
