java - How to change encryption algorithm for MapReduce Shuffle -


from our test, looks hadoop shuffle uses des encryption default: ecdhe-rsa-des-cbc3-sha:112,edh-rsa-des-cbc3-sha:112,des-cbc3-sha:112.

how set use aes?

are these correct ones set? hadoop.security.crypto.cipher.suite=aes/ctr/nopadding dfs.encrypt.data.transfer.cipher.suites=aes/ctr/nopadding

for aes use ecdhe-rsa-aes128-sha256 or ecdhe-rsa-aes256-sha384.

see supported ssl / tls ciphersuites section rsa elliptic curve ephemeral diffie hellman (ecdhe-rsa) key exchange.
