      Work Description: elek commented on issue #1568: HDDS-2225. SCM fails to 
start in most unsecure environments due to leftover secure config
URL: https://github.com/apache/hadoop/pull/1568#issuecomment-537393689
 
 
   Thanks @adoroszlai to fix this issue.
   
   Can you please help me to understand how is it possible. My assumption is 
that all the `core-site.xml` files are deleted after one test is executed. 
`docker-compose down` should delete all the previous state.

> 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.

> If secure tests are run last, the issue does not happen.
