Invalid CacheType: + cacheConfig.getCacheType()

Error message

Invalid CacheType: + cacheConfig.getCacheType()

What it means

Fall-through of the switch in createCachingFileSystem over cacheConfig.getCacheType(): the configured cache type is not one of the supported enum values (FILE_MERGE, ALLUXIO, etc.), indicating a misconfigured cache.type property.
