Failed: HBase all tests failed

[seglo]

All the HBase tests timed out on this build. Attached the log so the stage could be retried and not wipe out build info.

Happening in master too.

Build log has an error:

After I mapped the hbase to localhost in my /etc/hosts I was able to run the tests locally. Clue came from this failure of a java test.

IDK why this is all of a sudden necessary, or why the failure is transient in master.

EDIT: This was always necessary. The tests passed because I was using an older image of the hbase:1.4 tag.

Upstream docker image tag we rely on for integration tests was recently updated (1.4) https://hub.docker.com/r/harisekhon/hbase/tags

[ennru]

Yes, this seems to be a show stopper for all of our Travis builds. Looking into what they might have done at https://github.com/HariSekhon/Dockerfiles/commits/hbase-1.4/hbase

I've tried to revive the HBase tests locally with no success.

[ennru]

The HBase tests are excluded from the GitHub actions workflow, as well.

[ennru]

The HBase image the tests use doesn't work anymore and it doesn't seem maintained anymore https://github.com/HariSekhon/Dockerfiles/issues/42.

Furthermore, the versions of the Hadoop libraries Alpakka relies on are very outdated with CVEs reported for them.

[info] Found 4 dependency updates for akka-stream-alpakka-hbase

[info]   org.apache.hbase:hbase-shaded-client           : 1.4.13 -> 1.4.14 -> 1.7.1  -> 2.4.11

I'm inclined to remove the HBase connector altogether for Alpakka 4.0.

[ennru]

Just looked at this again, the Docker images haven't been touched and we are not verifying Alpakka HBase with integration tests.
