László Bodor updated HIVE-27295:
--------------------------------
Description:
1. While waiting for docker container to start properly, we should print the
output of docker logs command in every loop, otherwise we can miss important
information if the docker container is oom killed in the meantime. Not to
mention the fact that we're currently not logging the output at all in case of
an error:
https://github.com/apache/hive/blob/59058c65457fb7ab9d8575a555034e6633962661/itests/util/src/main/java/org/apache/hadoop/hive/ql/externalDB/AbstractExternalDB.java#L125-L127
2. We can include the output for docker events in the logs in case of an error
(like: oom killed container), which might contain useful information.
3. Consider adding a [--memory
option|https://docs.docker.com/config/containers/resource_constraints/] to the
docker run command with a reasonable value to make the RDBMS docker image
running process stable and independent from system settings.
