Description

Seems like MacOS(El Capitan) doesn't allow writing to /dev/urandom:

$ echo 1 > /dev/urandom
echo: write error: operation not permitted

Which is causing CipherFactoryTest failed:

$ ant test -Dtest.name=CipherFactoryTest

I'm able to reproduce the issue on two Mac machines. But not sure if it's affecting all other developers.

-Djava.security.egd=file:/dev/urandom was introduced in:
CASSANDRA-9581

I would suggest to revert the change as pig-test is removed (pig is no longer supported).
Or adding a condition for MacOS in build.xml.

aweisberg jasobrown any thoughts?
