The Hadoop official document recommends to set dfs.encrypt.data.transfer.cipher.suites to AES.
"AES offers the greatest cryptographic strength and the best performance."
Setting it to AES/CTR/NoPadding activates AES encryption. By default, this is unspecified, so AES is not used.
I wonder if the default need to be changed for security and performance. Thanks.
