      Description

      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.
