Resolution: Duplicate
> The implication of auth-conf is not followed in optimized HDFS data transfer
> encryption
> ---------------------------------------------------------------------------------------
>
> Key: HDFS-9900
> URL: https://issues.apache.org/jira/browse/HDFS-9900
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: encryption
> Affects Versions: 2.6.0
> Reporter: Jerry Chen
> Original Estimate: 672h
> Remaining Estimate: 672h
>
> HDFS-6606 provided an optimized way of HDFS data transfer encryption. The
> optimized encryption is build on top of SASL wrap/unwrap when auth-conf is
> configured.
> When user specifies auth-conf, he wants both integrity and confidential.
> While the current implementation of the optimization implements only
> confidential with AES/CTR and there is no integrity grantees, which means the
> implications of auth-conf were not strictly followed.
