Attila Doroszlai commented on HDDS-2086:
----------------------------------------
Hi [~avijayan], this can be reproduced using the current {{ozone-recon}}
environment, which has this configuration:
{noformat:title=https://github.com/apache/hadoop/blob/0e026cb0cefcadcfe404cd5d542f081f3b8ab69b/hadoop-ozone/dist/src/main/compose/ozone-recon/docker-config#L24}
OZONE-SITE.XML_ozone.recon.db.dir=/data/metadata/recon
{noformat}
{{/data/metadata}} does not exist in the image. Shouldn't Recon create it if
needed?
To reproduce the problem, simply run the tests:
{noformat}
$ cd hadoop-ozone/dist/target/ozone-0.5.0-SNAPSHOT/compose/ozone-recon
$ KEEP_RUNNING=true ./test.sh
{noformat}
Additionally an NPE occurs in {{ReconServer.stop}} when handling the
{{SQLException}} because {{httpServer}} is not initialized yet.
{noformat:title=docker-compose logs recon}
