So we do have the vulnerability with intermediate shuffles. However, this is temporary short lived data and may not pose a major issue depending on the customer/usecase.</P><P>If this is still a concern, then put the temp swap space to a separate disk and encrypt the disk at OS Level</P> Tue, 18 Oct 2016 22:52:07 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/When-I-want-to-do-hdfs-encryption-is-temp-swap-space-can-be/m-p/136950#M43845 egarelnabi 2016-10-18T22:52:07Z
