   > Consider one more scenario: restart and close file.
   > 
   > If the file has flushed an INT32 ChunkMetadata and a FLOAT ChunkMetadata and IoTDB is down when closing the file. When restart, the RestorableTsFileIOWriter will read the two ChunkMetadatas and try to merge them.

   Fixed. I noticed that there is no data type recorded in mod file and the version is not comparable, so that I get the current correct data type from MManager and delete the old wrong one in RestorableTsFileIOWriter.
