--------------------------------------
Summary: SCM fails to start in most unsecure environments due to
leftover secure config
Key: HDDS-2225
URL: https://issues.apache.org/jira/browse/HDDS-2225
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: docker
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
Intermittent failure of {{ozone-recon}} and some other acceptance tests where
SCM container is not available is caused by leftover secure config in
{{core-site.xml}}.
Initially the config file is
[empty|https://raw.githubusercontent.com/apache/hadoop/trunk/hadoop-hdds/common/src/main/conf/core-site.xml].
Various test environments populate it with different settings. The problem
happens when a test does not specify any config for {{core-site.xml}}, in which
case the previous test's config file is retained.

{code}
The problem is intermittent due to ordering of test cases being different in
different runs. If a secure test is run earlier, more tests are affected. If
secure tests are run last, the issue does not happen.
