> WAL should not be encrypted
> ---------------------------
>
> Key: SPARK-19520
> URL: https://issues.apache.org/jira/browse/SPARK-19520
> Project: Spark
> Issue Type: Bug
> Components: DStreams
> Affects Versions: 2.1.0
> Reporter: Marcelo Vanzin
>
> If I/O encryption is enabled in Spark (SPARK-5682), the write ahead logs
> written by streaming applications will also be encrypted.
> That creates issues because only the driver that wrote those files knows the
> key to decrypt them. So basically the WAL is unusuable in that scenario.
> Instead, the WAL should not be encrypted by Spark; if the user has a need to
> encrypt that data, other means (such as HDFS encryption zones) should be used
> instead.
