Thanks for the help Ulul/Daemeon,
Problem has sorted using lsof p <datanode pid> command.

Hi Be careful, HTTPS is to secure WebHDFS. If you want to protect all network streams you need more than that : <https://s3.amazonaws.com/dev.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.2/bk _reference/content/reference_chap-wire-encryption.html> https://s3.amazonaws.com/dev.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.2/bk_ reference/content/reference_chap-wire-encryption.html If you're just interested in HTTPS an lsof -p <datanode pid> | grep TCP will show you that DN listening on 50075 for HTTP, 50475 for HTTPS. For namenode that would be 50070 and 50470 Ulul Le 21/02/2015 19:53, hadoop.supp...@visolve.com <mailto:hadoop.supp...@visolve.com> a écrit : Hello Everyone, We are trying to measure performance between HTTP and HTTPS version on Hadoop DFS, Mapreduce and other related modules. As of now, we have tested using several metrics on Hadoop HTTP Mode. Similiarly we are trying to test the same metrics on HTTPS Platform. Basically our test suite cluster consists of one Master Node and two Slave Nodes. We have configured HTTPS connection and now we need to verify whether Nodes are communicating directly through HTTPS. Tried checking logs, clusters webhdfs ui, health check information, dfs admin report but of no help. Since there is only limited documentation available in HTTPS, we are unable to verify whether Nodes are communicating through HTTPS. Hence any experts around here can shed some light on how to confirm HTTPS communication status between nodes (might be with mapreduce/DFS). Note: If I have missed any information, feel free to check with me for the same.
