Subject Re: Support for non-secure Hadoop?

Yeah I'm whipping up an internal diff that rips out security stuff. I'll look into the shims
layer and if it's not too much burden to maintain post a diff with it.

I spoke with our Hadoop experts - unfortunately no on the Hadoop upgrade. Way too much inertia.

to support Hive since it doesn't have any security stuff also?
