It does not require us anything if nobody steps us to do it. :)

Re: [openstack-dev] [aodh] HBase gate job

[gord chung]

let's change this gate to experimental for now.

Hi,

So we recently decided to run the functional tests for the HBase driver
and enabled the gate job. It turned out the gate job didn't worked, so I
tried to fix it. Now it's almost fixed, and it run the functional tests
and Gabbi tests against Aodh with HBase as a back-end:

Obviously, as you know this is not a real HBase back-end, but a
in-memory backend that is provided inside Aodh. Now, it turns out that
this driver or this in-memory backend has a bug, as the Gabbi tests
fail.

I don't have time nor interest to fix that, so the way I see it it's
either:
1. Someone stands up, determines if the issue is in the driver or the
in-memory implementation and fix it
2. Nobody cares and we drop HBase gate and deprecates the driver

If nobody stands up in the next week, I'll start working on 2.

Yes, with my patch it should be pretty easy to reproduce.

Hi folks,

Sorry I missed the letter. I'll take a look on this. As I understand, it's
enough just to run functional tests to see the issue, right?

I prefer to deprecate all drivers except sql, but the upgrade issue
requires us providing some tools to migrate those existent data
