Re: [DISCUSS] Hadoop 3 and our dependencies generally
There is a 3.0.0-alpha4 release currently available as a non-snapshot version. I'm not sure it comes with API stability guarantees at all, IIRC the Hadoop community is planning on providing that for their betas.

+1 from me, too, but I'd like to review what actually changes in master for the migration to happen. I don't know much about Hadoop 3. I'm curious what the releases will look like (AFAIK, it's only snapshot builds right now; is that correct?), how our dependencies will change, and what API stability guarantees it offers.

+1 sounds like a good idea to me. On 8/3/17 10:08 AM, Sean Busbey wrote: Hi Folks! I think we need to start being more formal in planning for Hadoop 3. They're up to 3.0.0-alpha4 and are pushing towards API-locking betas[1]. What do folks think about starting to push on an Accumulo 2.0 release that only supports Hadoop 3? It would let us move faster, which we'll need to do if we want to get any API changes in to the Hadoop 3 line. If we get started soon we can probably make it parity on beta/GA status with the Hadoop 3 line. That would give us a beta for Accumulo Summit and GA by end of the year. Going to just Hadoop 3+ would also be a sufficient dependency break that we could do a pass updating any lagging dependencies to latest major version.

Re: [DISCUSS] Hadoop 3 and our dependencies generally
I am in favor of going to Hadoop 3 for Accumulo 2. If we do this then Accumulo 2 can not release until after Hadoop 3 does. Any idea when Hadoop 3 will release?

Re: [DISCUSS] Hadoop 3 and our dependencies generally
All, For what it's worth, I'd attempted to run both 1.7.x and 1.8.x on Hadoop 3 and ran into a fairly straightforward dependency issue [1] that, when addressed, should allow current Accumulo versions to run on Hadoop 3. Hopefully this means that it's not a large lift to get to the point you're aiming for.
