周沛辰 commented on IOTDB-4738:
----------------------------
Write a value page first, which has no statistics, and then write an empty
value page. When reading this file, the system will think that these two pages
have their own statistic, but they do not, so an error will be reported.
> TsFile damaged after writing empty value pages
