> Spark uses commons-codec 1.5, which has a race condition in Base64.  That race was introduced
in commons-codec 1.4 and resolved in 1.7.  The current version of commons-codec is 1.10.
> Code that runs in Workers and assumes that Base64 is thread-safe will break because spark
is using a non-thread-safe version.  See CODEC-96
> In addition, the spark.files.userClassPathFirst mechanism is currently broken, (bug to
come), so there isn't a viable work around for this issue.
