Sandboxed network classloaders were a big win for Hadoop and Spark.
- ptx 7y agoIs the JVM's sandboxing still supported, patched and believed to be secure? I had assumed they gave up on it when they removed applet and webstart support.
- erik_seaberg 7y agoThought it over and you're right, Spark has some SecurityManager glue I've vaguely glanced at, but HDFS relies more on Kerberos than anything in-proc with the workers. IPC into an opaque worker binary would be a lot more painful but can be made to work.
