> When testing and comparing the performance of different file systems(HDFS,
> Azure blob storage, AWS S3 and so on) for HBase, it's better to avoid the
> affect of the HBase BlockCache and get the actually random read latency when
> data block is read from underlying file system. (Usually, the index block and
> meta block should be cached in memory in the testing).
> So we add a option in CacheConfig to disable the data block cache.
> Suggestions are welcomed~ Thanks
