Hi @Jay SenSharma, I tried the "recursive=true" parameter, but it doesn't give any different response. It is identical with the response from API without "recursive=true" and my question was to find a file or directory within a given directory. I have updated my question to give you more clarity. Hope it helps. Thanks!

How do I search for a filename or directory name recursively in a given path in WebHDFS? For example: If I search for "hive" from the root directory "/", I expect a response with directory names or file names matching "hive" under "/" such as /hdp/apps/2.6.0.1-89/hive
/hdp/apps/2.6.0.1-89/hive/hive.tar.gz
