> Node Labels root directory creation doesn't have a retry logic

> Key: YARN-11463
> URL: https://issues.apache.org/jira/browse/YARN-11463
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacity scheduler
> Reporter: Benjamin Teke
> Assignee: Ashutosh Gupta
> Priority: Major
> Labels: pull-request-available

> When CS is initialized, it'll [try to create the configured node labels root
> dir|https://github.com/apache/hadoop/blob/7169ec450957e5602775c3cd6fe1bf0b95773dfb/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/nodelabels/store/AbstractFSNodeStore.java#L69].
> This however doesn't implement any kind of retry logic (in contrast to the
> RM FS state store or ZK state store), hence if the distributed file system is
> unavailable at the exact moment CS tries to start it'll fail. A retry logic
> could be implemented to improve the robustness of the startup process.
