Possibly. Being rather explicit about what we support is definitely good; finding out when we accidentally break something we're supposed to support... also a good idea. :D

I'm almost of the mindset to not really encourage people to use 0.20.205 hadoop things anymore, maybe? I have no idea what 1.0 and 1.1 (even 0.23 or 2.0) adoption of Hadoop in the community looks like these days.

Likely. I just followed the directions in the README as I have not kept up with 
all of the changes in 1.5. It seems that maybe we should have Jenkins build 
with all of the different profile variations, or at least the ones that we use 
as examples in the README.

I wish I could tell you that it worked on my machine, but alas the
command below did fail on a bunch of core tests via
Accumulo*FormatTest$MRTester.

Looking into it currently. Maybe someone accidentally broke
compatibility with the old Hadoop stuff and we need to add a new
dependency with 0.20.205.0?

Has anyone else seen this?

We have tests for dynamic loading of classes so I'm pretty sure it works.

John, can you repeat the failure?

Looking at the code, it should work. Keith and I had several conversations
about what the new classloader should do. I believe that he wanted it to
behave like the old one and what I see in the code supports that. If it is
not working, then I would say create a ticket for it for now. I'll try to
replicate it tonight if I have time.

The implementation changed several times, so the pre-1.5 layout may not
work. In 1.5, using the bootstrap script, it should put the accumulo jars
into HDFS and dynamic loading from there should occur. I'll try and test
tonight if I have time.

Maybe I missed something with the switch to the VFS classloader, but does
dynamic loading out of lib/ext no longer work? I had accumulo 1.5 running,
threw an iterator in there, but had to restart tserver to get the new
iterator picked up. Was that an intentional change?
