>                 Key: SPARK-19520
>                 URL:
>             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.
