I believe it would be in our best interest to move to .203+ in order to benefit from Kerberos
security.

Well, I spoke two soon. There are two pending tickets on my plate (Accumulo-404, running on
top of kerberoized hdfs and Accumulo-489, passwords are not secured with input format) that
are a lot easier to implement, if not only feasible, against 20.203+ (CDH3u0+). It is possible
to do version checking within the code and then calling via reflection, but that is ugly,
ugly code that I think we'd be best to avoid. So I ask the community, do we have any reasons
NOT to migrate our minimum version to 20.203 now that we have a need for a newer version?

I was just interested since 0.20.2 is now two years old if there was any compelling reason
(other than QA requirements) to stay with that version

We don't depend on any specific features of 20.205, so I don't know why we need to update
the minimum version. I know many of us have been working with 20.205 without issue.

I haven't looked at the 1.4 branch in detail, did you guys move to a newer version of Hadoop
as well, the 1.3.5 release uses the comparatively ancient 0.20.2 version of Hadoop

Yes, the 1.4 branch is considered stable.

We've been pounding on 1.4 for quite a while.  The scale of the testing has over a longer
period of time, more complete and more aggressive. Another team has been using it for some
benchmark testing at scale, and it is remarkable for the *lack* of problems.

No, you cannot mix 1.3 clients with 1.4 servers.  We jumped from 0.3 of thrift to 0.6.1, and
that was a huge change for us; I'm not even sure if it can be on-the-wire compatible.  Our
goal is to ensure compatibility for 1.X.* level for any constant X.  But a switch from 1.X
to 1.Y... we'll remove deprecated APIs, and break on-the-wire compatibility.

Is the 1.4.0 branch considered stable enough for use?  And is it the API compatible between
1.3.5 and 1.4.0 or do both the database and the client need to be on the exact same version
for communication to work correctly?

I believe we don't have them distributed because our poms do not include adequate licensing
info for us to publicly release them. 1.4.0 should be released when we release it though.

Is there a reason why Maven artifacts for 1.3.5 are not available in the Apache repositories?

Which Maven repositories (if any) are they available in?
