Francis Chuang commented on CALCITE-1950:
-----------------------------------------
This is still a problem with HSQLDB 2.4.0. I have opened CALCITE-2250 and
included a bash script as well as all the protobuf messages to reproduce. I
think we should continue the discussion over there.
> Avatica HSQLDB docker image hangs
> ---------------------------------
>
> Key: CALCITE-1950
> URL: https://issues.apache.org/jira/browse/CALCITE-1950
> Project: Calcite
> Issue Type: Bug
> Components: avatica
> Reporter: Francis Chuang
> Assignee: Josh Elser
> Priority: Major
>
> I am using the calcite-avatica hsqldb image here:
> https://hub.docker.com/r/f21global/calcite-avatica/
> The image is built using this docker file:
> https://github.com/apache/calcite-avatica/tree/master/docker/src/main/docker/hypersql
> I am currently running integration tests for the Go client against that
> image. It seems that after a certain amount of operations, the server will
> lock up. From the Go http client, it seems that avatica no longer responds.
> There wasn't any interesting information when I ran `docker logs` on the
> container avatica/hsqldb is running in.
> When it starts hanging, tests that were passing previously would fail
> randomly, because the test is not able to get a response form avatica.
> Usually, deleting and recreating the container would resolve the problem, but
> after using the same container through a few more test cycles, it starts to
> hang again.
