问题
I have a set of directories created in HDFS recursively. How can list all the directories ? For a normal unix file system I can do that using the below command
find /path/ -type d -print
But I want to get the similar thing for HDFS.
回答1:
To list directory contents recursively hadoop dfs -lsr /dirname command can be used.
To filter only directories , you can grep "drwx" (since owner has rwx permission on directories) in output of above command.
Hence whole command will look like as below.
$hadoop dfs -lsr /sqoopO7 | grep drwx
回答2:
The answer given by @Shubhangi Pardeshi is correct but for latest hadoop version command has deprecated. So new latest command can be used as below
hdfs dfs -ls -R /user | grep drwx
