I find out this error is related with starting the same IoTDB server twice. When the first IoTDB is flushing TsFile, the second IoTDB finds there is WAL file existed and then flush the same TsFile again. Therefore, this error will appear.

> When restarting IoTDB and flushing the wal, the io task meets error. 
> It throw a RuntimeException, however, this exception is not catched by TsFileProcessor, TsFileProcessor still ends the file, which causes a corrupt tsfile.
