-------------------------------------
Summary: CSMapping rule can return paths with empty parts
Key: YARN-10635
URL: https://issues.apache.org/jira/browse/YARN-10635
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Gergely Pollak
When a variable to be substituted evaluates to empty string, we might result
with paths where one of the parts is empty, these paths are obviously
problematic, but sometimes (when the path includes a dynamicParent) we accept
them as valid paths instead of getting the fallback action of the rule.
