Also, you can check out the builds/runs here: https://app.wercker.com/F21/calcite/runs

The failures earlier were due to me adjusting the wercker config.

Francis,

Try removing the depth argument when you do 'git clone'.

I tried to force travis to use a standard trusty vm in 
https://github.com/apache/calcite/pull/293, so that the VM is assigned 7.5GB of 
memory. Unfortunately, travis is still quite flaky, with tests only passing 
some of the time.

Would it be useful to move to another CI? I tried setting up my fork to use 
wercker: https://github.com/F21/calcite/blob/use-wercker/wercker.yml which 
failed here:

Unfortunately, I haven't found a solution to this error:

I’ve noticed it. A lot of Travis builds seem to hang. See the last two lines of 
https://travis-ci.org/apache/calcite/jobs/163844678: 
<https://travis-ci.org/apache/calcite/jobs/163844678:>

  No output has been received in the last 10 minutes, this potentially
indicates a stalled build or something wrong with the build itself.

The build has been terminated
I don’t know why Travis does this. I suspect that the Travis VM doesn’t have 
enough memory to complete the task, or the job takes longer than Travis allows, 
but these are wild guesses.

I have been running the build and tests on my own Linux server in a variety of 
configurations (in particular JDK 1.7 and 1.8, and a couple of timezones, and 
occasionally also on macOS and Windows), and I can confirm that everything is 
stable.

Hi,

I just opened a pull request against Calcite master, and the travis build
failed. But then I checked the master branch, and according to Travis, it's
also failing.

Is it something known, or just a transient issue?

Thanks in advance,

Laurent
