> [~vrodionov] added some API to {{CacheConfig}} via HBASE-17151 to allow
> callers to specify that they do not want to use a block cache when reading an
> HFile.
> If the BucketCache is set up to use the FileSystem, we can have a situation
> where the client tries to instantiate the BucketCache and is disallowed due
> to filesystem permissions:
