[jira] [Created] (HBASE-21981) MMaped bucket cache IOEngines does not work with persistence

ramkrishna.s.vasudevan created HBASE-21981:
----------------------------------------------

             Summary: MMaped bucket cache IOEngines does not work with persistence
                 Key: HBASE-21981
                 URL: https://issues.apache.org/jira/browse/HBASE-21981
             Project: HBase
          Issue Type: Bug
          Components: BucketCache
    Affects Versions: 2.1.3
            Reporter: ramkrishna.s.vasudevan
            Assignee: Anoop Sam John
             Fix For: 3.0.0, 2.2.0, 2.0.5, 2.3.0, 2.1.4


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.
