freemandealer opened a new pull request, #44429:
URL: https://github.com/apache/doris/pull/44429
The original paralleled cache init will causing unstable pick of cache base
path because the choice depends on the order of init which could be different
after each BE reboot. Thus, cause cache missing and duplicate cache block
across multiple caches (disk space waste).
This commit will serialize the init process of multiple cache and using
fixed order, i.e. the order explicitly declared in be conf: file_cache_path.
