> Project: Ambari
> Issue Type: Bug
> Components: ambari-agent
> Affects Versions: 3.0.0
> Reporter: Doroszlai, Attila
> Assignee: Doroszlai, Attila
> Priority: Critical
> Fix For: 3.0.0
>
> Attachments: AMBARI-19372.patch
>
>
> Ambari agent's {{FileCache}} is not thread-safe, hence needs to be disabled
> if {{parallel_execution}} is enabled. The server's
> {{agent.auto.cache.update=false}} setting is not enough to prevent all
> subprocesses from using the file cache, because they are started before the
> setting is received from the server.
