>
> currenttly if we call org.apache.hadoop.hbase.io.hfile.HFileReaderImpl#midKey
> on an empty HFile, we got an exception like
> java.io.IOException: HFile empty
> since the function return an Optional<Cell> , I think it's better return
> Optional.empty() instead of throw An Exception
> when a region with muiltiple column family grow big enough to be splited, if
> got some empty column family, will got some warn log like this
> java.io.IOException: HFile empty at
> org.apache.hadoop.hbase.io.hfile.HFileBlockIndex$BlockIndexReader.midkey(HFileBlockIndex.java:334)
> sinece exception is catched, split logic will go on and got right result
