> Components: BucketCache
> Affects Versions: 2.1.3

> The MMap based IOEngines does not retrieve the data back if 'hbase.bucketcache.persistent.path' is enabled. FileIOEngine works fine but only the FileMMapEngine has this problem.
> The reason is that we don't get the byte buffers in the proper order while reading back from the file in case of persistence.
